Slap Battles Easter Update April 2026 — Shellbert Glove & The Fourth Trial

By Earnaldo Team • April 12, 2026 • 10 min read

Slap Battles dropped its Easter update on April 10, 2026, introducing a new subplace, a multi-phase boss fight, and a brand-new badge glove called Shellbert. The update expands the existing Egging Over It event with a fourth challenge — aptly named The Fourth Trial — that sends players into a nest-like arena to face off against a giant chicken. Survive both phases, collect the cracked-egg glove from the arena floor, and you'll walk away with the Easter Hatchastrophe badge and one of the most unique gloves in the game. This guide covers everything: prerequisites, step-by-step boss walkthrough, Shellbert's full ability kit, and the balance changes that shipped alongside the event.

Update Overview

The April 10 update for Slap Battles is built entirely around Easter theming and is the most substantial event content the game has received since the original Egging Over It launch. At its center is The Fourth Trial, a dedicated subplace that functions as a boss-rush arena distinct from the normal lobby. The update also shipped a suite of balance patches to several popular gloves, including major reworks to Chain Mastery, significant nerfs to Wheelchair, and cooldown adjustments to Eggler.

The headline addition is Shellbert, a badge glove that looks like a cracked open egg with a yolk visible on the back of the hand. It's obtained exclusively by earning the Easter Hatchastrophe badge — which itself requires completing The Fourth Trial. There is no other way to get it, and it won't be available through the normal glove shop. If you want Shellbert, you need to run the event.

It's worth noting that this update also closes the loop on the broader Easter storyline. The original Egging Over It event introduced the egg-hunting quest, the Eggler glove, and the character Kenneth. The Fourth Trial resolves Kenneth's quest arc and puts a proper boss encounter at the end of the Easter content chain.

Prerequisites — Getting Eggler First

Before you can even think about The Fourth Trial, you need the Eggler glove. The gate is hard — the portal to The Fourth Trial will not appear unless you already own Eggler. There are no workarounds. If you're missing it, here's the full path to earn it.

Eggler was added to Slap Battles on April 18, 2025 as part of the original Egging Over It event. To earn it, players must complete the Easter Egg Hunter quest by collecting 10 Easter Eggs hidden around the Normal Arena. The eggs don't announce themselves — you need to explore the map carefully or follow a community egg-location guide.

1. Visit The Hitman NPC in the Normal Arena and accept the Easter Egg Hunter challenge to start the quest
2. Find and collect all 10 Easter Eggs scattered across the Normal Arena map
3. Return to The Hitman NPC once all 10 eggs are collected to complete the quest — a toy Eggdog will appear
4. Follow the Eggdog into the secret area and interact with Kenneth NPC to transform into an egg
5. Complete all 3 trials inside Egging Over It, collecting the golden egg at the end of each trial
6. After all 3 golden eggs are in hand, talk to Kenneth again to claim the Egging Over It badge and unlock the Eggler glove

Eggler itself has 55 Power and 15 Speed stats. It also has its own ability kit that lets you capture and throw players with a tongue grab. Note that the April 10 update added cooldowns to Eggler's E and R abilities and reduced its tongue range and grab speed by 25%, so if you played it before this patch the mechanics will feel slightly different now. Players can also jump over a mastered Eggler tongue as of this update.

Egging Over It & Kenneth NPC

Once you have Eggler equipped or in your inventory, head into the Egging Over It event area and find the NPC Kenneth. He's the key to opening the portal to The Fourth Trial. The interaction is dialogue-gated — you'll need to select specific choices in the conversation to trigger the portal spawn.

To open the door to The Fourth Trial, talk to Kenneth and make sure you already have all 3 golden eggs from the original Egging Over It trials. Then, when the dialogue options appear, choose option 1, option 1, and option 1 in sequence. After those three selections, a portal will appear in the area. Walk through it to enter The Fourth Trial subplace and begin the boss encounter.

The portal doesn't stay open permanently — once you enter, you'll be instanced into the boss arena. If you leave without collecting Shellbert, you'll need to summon the portal again through Kenneth. That means the same dialogue sequence must be repeated, so it's worth going in prepared rather than treating it as a practice run.

The Fourth Trial — Boss Fight Walkthrough

The Fourth Trial drops you into a round, nest-like arena. The outer ring of the arena is lined with obbies (obstacle course segments), while the center is cleared out. In the middle sits a giant chicken — the boss. The encounter kicks off with a cutscene where you slap the chicken to wake it up, transitioning immediately into Phase 1.

Phase 1 — Obby Mechanics

Phase 1 is more of a movement challenge than a direct combat encounter. The obbies on the outer ring are the primary way to deal damage to the boss during this phase. Navigate the obstacle sections, survive the boss's attack patterns, and work through each obby segment while keeping an eye on what the chicken is doing.

The boss has a stomp attack in Phase 1. If you're near the chicken when it stomps, you take damage and knockback. The best counter is to dash away rather than jump — jumping doesn't create enough horizontal distance to clear the stomp radius. Learn this early because the behavior carries over with increased intensity in Phase 2.

The goal in Phase 1 is to chip down the boss's HP through the obby mechanics while staying mobile. Don't rush straight at the chicken — the obbies are intentional and dealing damage through them is the intended design of this phase.

Phase 2 — Direct Slapping

Phase 2 triggers after enough damage is dealt in Phase 1. When the transition happens, all of the obbies are destroyed and the chicken loses its shell. With no outer ring left, the arena becomes a flat open space. The shell-less chicken can now be damaged directly through slaps, dealing 4–5 HP per slap.

Phase 2 introduces two major threats. First, the boss can now spawn egg minions that wander the arena and explode on contact with players, dealing damage and knockback. Keep an eye on their positioning and don't let them sneak up on you while you're focused on slapping the boss. Second, the chicken's stomp is stronger than in Phase 1. The dash-instead-of-jump rule is even more important here — especially when you're in close range trying to deal slap damage.

The strategy for Phase 2 is to stay aggressive on the boss while managing your positioning around the egg minions. Don't chase minions unless they're directly in your path — the boss HP pool is the only thing that matters. Keep slapping, keep dashing away from stomps, and prioritize staying alive over maximising DPS.

Boss Defeat & Shellbert Reward

Once the chicken's HP reaches zero, the boss does not immediately disappear. It winds up to launch a final attack — but before it connects, Kenneth appears and defeats the chicken himself. This scripted sequence closes out the boss fight. After Kenneth's intervention, the Shellbert glove spawns on the arena floor. Walk over to it and collect it to claim the Easter Hatchastrophe badge and add Shellbert to your glove collection. You'll then be automatically sent back to the Egging Over It area.

Shellbert Glove — Stats & Abilities

Shellbert is a badge glove, meaning it's permanently tied to the Easter Hatchastrophe badge and can only be equipped by players who've earned it. The glove's visual design reflects what you fought for: it looks like a cracked-open egg with a visible yolk sitting on the back of the hand. It's one of the more distinct-looking gloves in Slap Battles.

The ability kit is where Shellbert gets interesting. It has 1 passive and 3 active abilities, with the active abilities cycled through using the [R] key. Each ability leans into the egg theme in a different way.

Passive — Egg Transformation

Equipping Shellbert transforms your character into an egg. The egg form is notably smaller than Elf (one of the smallest baseline character forms in the game), which changes your hitbox and makes you harder to hit at certain angles. In egg form, you roll rather than walk — movement is slightly slower than standard players, but you alternate between a slow period on your base and a faster period when rolling on your tip.

The key defensive property of egg form is the knockback cap. No matter how powerful the opponent's glove is, you take only 50–55 knockback from any slap. The trade-off is a 1.5-second stun after each hit. You won't go flying across the map, but you will be briefly immobile. Managing that stun window — knowing when you're about to get hit and positioning accordingly — is the core skill challenge of playing Shellbert effectively.

Active Abilities

*Abilities are cycled using [R] before pressing [E] to use.

The Yolk Blast is best used for repositioning. In egg form your movement is already slower than opponents, so having a burst-movement ability keeps you from being stuck in corners. It's also useful for escaping stun windows after taking a hit.

Eggsplode is an offensive tool with a notable drawback: it shrinks your size and reduces your slap range after use. In a game where reach matters for landing slaps before opponents can respond, the range penalty is significant. Use it as a crowd-control option when multiple players are close rather than as a primary damage tool in 1v1 situations.

Balance Changes in the April 10 Update

The Shellbert update wasn't just event content — it shipped with a substantial round of balance patches affecting several of the most-played gloves. Here's a breakdown of what changed.

Thanos

Power boost effects now properly fade out instead of abruptly ending. Thanos players can now use the E ability while ragdolled, which was a quality-of-life gap the community had flagged for some time. Mind Pulse was changed to apply the parry stun mechanic instead of ragdolling targets. Spatial Return now pulls players equally regardless of their weight stat — previously heavier gloves had an unintended resistance to being pulled.

Eggler & MEggler

Both versions received cooldowns on the E and R abilities. The tongue's range and grab speed were reduced by 25%, and players can now jump over a mastered Eggler tongue. These changes were aimed at addressing complaints that a skilled Eggler player could lock down opponents with little counterplay. The quest requirement for Egging Over It was also reduced from 150 to 100 alongside these nerfs.

Chain Mastery (Major Rework)

Chain Mastery received the most significant changes of the patch — effectively a full rework of its ability kit. A new passive called Electrical Potential generates energy orbs (up to a maximum of 12) whenever you zap enemies. A new E ability, Tesla Orb, fires an electric sphere that zaps nearby enemies and spreads damage through chain lightning. The size and range of Tesla Orb scales with how many stored orbs you have, and activating it consumes all of them. This creates a charge-and-release playstyle that rewards sustained engagement over burst-and-retreat tactics.

Wheelchair

Wheelchair received across-the-board nerfs. Power was dropped from 57 to 52. The slap now triggers at the end of a dash rather than during it, and requires direct player contact to register — previously it could catch players slightly off to the side. Knockback resistance was cut from 40% to 20%, making Wheelchair players significantly easier to send flying than before.

Tips & Strategies

For New Players Attempting The Fourth Trial

Don't rush Phase 2. When the obbies are destroyed and you have open space, it can feel like the right move is to sprint at the boss and slap as fast as possible. Resist that instinct. The egg minions will spawn and if you're deep in the center, they can corner you with no escape angle. Stay near the outer edge of the arena, bait the boss toward you, and deal your slap damage in short bursts before resetting your position.

Bring a glove with good mobility if you're able to swap before entering the portal. Shellbert is the reward, not the tool. You'll be using your current glove for the entire boss fight, so something with a dash or movement ability will make Phase 2 much more manageable than a slow, high-power pick.

For Players Who Already Have Shellbert

Shellbert works best in chaotic multi-player lobbies where opponents are focused on slapping each other. The knockback cap in egg form means that even stray slaps from powerful gloves won't knock you out, while a well-timed Eggsplode in the middle of a group can scatter multiple players at once. In 1v1 situations, the slap range reduction from Eggsplode becomes a liability, so lean more heavily on Yolk Blast for repositioning and standard slaps for damage.

The 1.5-second post-hit stun is the biggest thing to account for when playing Shellbert. Position yourself near walls or ledges where opponents might naturally retreat after slapping you — that way the stun window doesn't expose you to an immediate follow-up slap from the same player.
