SpongeBob Tower Defense Tier List (2026) — Best Units Ranked

SpongeBob Tower Defense keeps adding units faster than most players can roll for them, and the meta has shifted hard after the UPD 22 patch in May 2026. The wrong lineup will leak enemies by wave 20. This tier list ranks every unit worth slotting on your track, from the Secret heavy-hitters down to the legacy picks that fell off, current as of June 2026.

We ranked each unit on damage per second, range, attack type (single target, splash, line, or full AoE), and how it holds up in endgame modes on Roblox. If you need active SpongeBob Tower Defense codes for free coins and gems before your next summon session, we keep that list updated daily.

S Tier — Best Units in SpongeBob Tower Defense

These units carry the current meta. They mix high damage with full or splash AoE, which is exactly what you want when waves pile up. If you're clearing the hardest modes, build your whole track around two or three of these.

Baby Pearl (Secret)

Baby Pearl is the single hardest hitter in the game right now. She deals 44,000 damage per shot at a blistering 0.7 second attack speed, and her 46 range is the longest of any top unit. That combination of speed, damage, and reach lets one maxed Baby Pearl cover most of a map by herself.

Her attacks are splash AoE, so she's not quite as efficient against tightly grouped swarms as a full-AoE unit. But the raw numbers are so far ahead of everything else that she earns the top slot anyway. If you pull one, build around her immediately.

MimicBob (Exotic)

MimicBob is the best full-AoE carry in the meta. He hits every enemy in a 31 range circle for 25,000 damage each at 1.2 attack speed. Full AoE means crowded waves melt instantly, and his Exotic rarity makes him slightly more reachable than the rarest Secrets.

Place MimicBob on a corner where the track loops back on itself. Enemies pass through his range twice, doubling his effective uptime. That positioning trick turns an already top-tier unit into a wave-ending machine.

Mega-Hydra Karen (Exotic)

Mega-Hydra Karen is the other Exotic worth chasing, dealing 20,000+ splash damage on a 1.5 second cooldown with 30+ range. She trades a little speed for huge per-hit numbers, which makes her excellent against boss waves where a few massive splashes finish the job fast.

Rrarrg (Secret)

Rrarrg brings 25,200 full-AoE damage at 1.5 attack speed across 28 range. He's the closest thing to MimicBob in raw clearing power, and on maps with long straightaways his range edge actually pulls him ahead. Two Rrarrgs on opposite corners shut down almost any standard wave.

Dennis & Hash Slinging Slasher (Secret)

Dennis deals 9,500 full-AoE damage with a burn effect at 1.8 speed and 24 range, while the Hash Slinging Slasher puts out 8,400 full AoE plus burn at a faster 1.0 speed over 25 range. Both stack damage-over-time on top of their hits, which chews through tanky enemies that survive the initial blast. Burn ignores armor, so these two stay relevant even when enemy HP scales up.

Alaskan Bull Worm & Sea Bear (Secret)

The Alaskan Bull Worm hits for 10,500 pierce AoE with a Frostbite slow at 1.9 speed and 22 range. The slow is the draw here. Freezing a wave in place lets your damage dealers get extra shots off before enemies reach the exit. Sea Bear rounds out the Secret tier with 7,000 splash AoE at a quick 1.0 speed and a long 28 range, making him a reliable secondary carry.

SpongeHenge & Dream Gary (Secret)

SpongeHenge deals 4,125 full-AoE damage at 1.5 speed over 16 range. The damage looks modest next to Baby Pearl, but full AoE on every shot makes him a consistent wave-clearer on compact maps. Dream Gary is the premier support pick: 1,216 splash damage with a strong slow effect at 1.5 speed and 17 range. Drop Gary near a choke point and your DPS units get far more value out of every enemy that crawls through.

S-tier Secret and Exotic units carry the 2026 meta

A Tier — Excellent Units

A-tier units won't headline an endgame track, but they're strong, reliable, and far easier to obtain than the Secrets above. Several fill roles that make your S-tier carries hit harder.

Fishnet Patrick (Limited)

Fishnet Patrick deals 6,600 full-AoE damage at a slow 2.0 attack speed over 24 range. The cooldown holds him back from S tier, but full AoE at that damage is excellent value, especially since he was a Limited unit that many players already own from an earlier event.

Bubbles The Dolphin, Sea Rhino & Richard (Mythical)

Bubbles The Dolphin and Richard both deal around 2,400–2,500 line-AoE damage, hitting everything in a straight line through their range. Line units are best on long straight track segments where enemies file in single column. Sea Rhino brings 2,500 pierce AoE at 1.8 speed and a generous 28 range, which makes him the most flexible of the three. As Mythicals, all three are realistic pulls for mid-game players building toward a Secret roster.

A-tier Mythicals fill key roles on the way to an endgame lineup

B Tier — Early & Mid Game Picks

B-tier units are your workhorses before the Secrets show up. A well-placed B-tier unit clears early waves just fine, and a couple of them stay useful well into mid-game.

Band Geek SpongeBob (Legendary)

Band Geek SpongeBob is the best non-Mythic carry you can build around early. He deals 1,873 line-AoE damage at 1.5 speed over 25 range, and Legendary rarity means you'll pull one without grinding hundreds of summons. He carries most players through the early and mid stages.

GG Rock SpongeBob & Band Geek Mr. Krabs (Mythical)

GG Rock SpongeBob has an absurd 0.3 attack speed — the fastest in the game — firing 1,480 line-AoE damage almost continuously over 24 range. On a long straightaway he's a shredder. Band Geek Mr. Krabs adds 950 splash damage at 1.5 speed and 16 range, a solid early splash option to pair with line units.

The Quickster & Soaring Starfish

The Quickster is a budget full-AoE Mythical at 540 damage and 16 range, useful for cheap early coverage. Soaring Starfish, a Limited seasonal unit, deals 1,600 splash damage at 1.5 speed over 25 range and outperforms its tier when you can still get it.

C Tier — Power-Crept & Situational

C-tier units have been left behind by newer releases. These are older Legendaries and lower rarities that simply can't keep pace once enemy HP scales up.

Spongegar, Mermaid Man, Band Geek Patrick, and Atomic Flounder were all viable in earlier patches but have been power-crept by the UPD 22 additions. They still function as placeholders while you grind for better units, just don't invest coins maxing them out.

Older event and starter units like King Neptune and DoodleBob sit at the bottom. They're fine for your very first few waves, but you'll want to bench them the moment a Mythical or better comes along. Common and Uncommon units belong here too — treat them as fodder for the early game and nothing more.

Matching the right unit to each map decides your run

Tier List Summary Table

How We Ranked These Units

This tier list reflects the SpongeBob Tower Defense meta as of June 2026, after the UPD 22 patch in May added the Exotic rarity and several new boss and seasonal units. Here's what we weighed:

Damage and attack speed: We calculated effective DPS, not just the per-hit number. Baby Pearl's 44,000 at 0.7 speed crushes everything, but GG Rock SpongeBob's 0.3 speed shows why attack rate matters as much as the damage stat.

Attack type: Full AoE beats splash beats line beats single target on most maps because it hits more enemies per shot. We weighted full-AoE units like MimicBob and Rrarrg higher, then adjusted line units down since they need straight tracks to shine.

Utility: Slows and burns punch above their damage numbers. Dream Gary and the Alaskan Bull Worm earn S-tier slots largely on crowd control, and the burn units stay relevant against high-HP waves because damage-over-time ignores armor.

Accessibility: We note rarity so you can set realistic goals. You don't need the rarest Secrets to clear most content — a Legendary like Band Geek SpongeBob plus a couple of Mythicals will carry you a long way while you grind summons.
