Spongebob Tower Defense on Roblox features many units for you to unlock, but which ones offer the best stats for you to use to sail through Chapters?
Spongebob Tower Defense offers 65 units after Update 8, including the three starters for you to choose from. Each unit has a rarity of Common, Uncommon, Rare, Epic, Legendary, Limited, Mythic, or Secret.
Like most Roblox games, you’re better off sticking to Legendary and above characters. As the rarity suggests, Mythic and Secret are some of the best options available, with Uncommon and Rare only serving you well for the first couple of hours of hopping into the game. With the Standard and Booster summoning banners refreshing daily, you must use your hard-earned gems wisely.
That said, here’s our Spongebob Tower Defense tier list, ranking all the units from best to worst.

Best units in Spongebob Tower Defense: S-tier
| Unit | Why it’s one of the best | Stats |
|---|---|---|
| SpongeHenge | It’s undoubtedly the best unit in Spongebob Tower Defense thanks to its massive AoE damage and amazing range. With the correct placement of a SpongeHenge unit, you can cover the entire map and incinerate incoming waves within seconds. However, it’s incredibly hard to obtain—except trading for high-value units, you can only get SpongeHenge using the Prestige Shop (at Max Prestige) which requires Prestige Tokens. | Price: 1,750 DMG: 4,354 SPA: 1.3 RNG: 30 |
| Captain Magma | Offers incredible AoE damage output but lacks the range of some of the best units. Still, its range with a few upgrades is enough to make quick work of the incoming waves. | Price: 1,250 DMG: 1,832 SPA: 2.5 RNG: 15 |
| Band Geek Mrs. Puff | Arguably the best Mythic unit after Update 8 went live. It offers damage and range better than the Secret units, making it one of the best picks for any mode. | Price: 1,250 DMG: 1,867 SPA: 2 RNG: 26 |
| GG Rock Spongebob | If luck’s not on your side and you’re unable to get a Secret unit, don’t worry; GG Rock Spongebob offers everything a meta unit needs: Line AoE attacks, incredible range, negligible time between consecutive attacks, and massive damage. | Price: 1,250 DMG: 1,591 SPA: 0 RNG: 24 |
| Hibernation Sandy | It’s an amazing Mythic unit to rock in Spongebob Tower Defense that can compete with Secret units because of its great damage and equally impressive range. | Price: 1,250 DMG: 919 SPA: 2 RNG: 22 |
| Mermaid Man | Compared to the other Mythics, Mermaid Man is fairly easy to roll—which is the only reason it’s in our S-tier. Considering its lackluster range and attack AoE, we can easily drop him into the A-tier. | Price: 1,250 DMG: 1,396 SPA: 3 RNG: 12 |
| Realistic Fish Head | Don’t be deceived by its base stats. This unit’s stats significantly improve upon leveling. Considering it’s a Full AoE unit, it dishes out heaps of damage, making it an incredible pick, especially for the infinite mode. | Price: 1,250 DMG: 520 SPA: 2 RNG: 10 |
| Cyborg Plankton | The worst Secret unit out of the three in total, but it still offers impressive range and damage, one-upping almost every Mythic. | Price: 1,750 DMG: 563 SPA: 1.5 RNG: 33.8 |
| Dream Gary | With its AoE damage and slow, accompanied by incredible damage, it’s one of the best units available through the Exclusive Summons’ banner. | Price: 1,750 DMG: 1216 SPA: 1.5 RNG: 17 |
A-tier units
The A-tier units are mostly Legendary and Mythic, with most of them offering considerably less damage than the ones in the S-tier. However, you can add stack these units with ease by simply farming Gems or leaving the game running for AFK rewards.
I recommend farming an Act, which you can complete in under two minutes, for at least a couple hours. You’ll have enough Gems to roll a Legendary or even Mythic unit. Don’t worry; like most Roblox games, the pity bar ensures that with enough attempts, you are guaranteed a rare unit.
Additionally, the A-tier units are a stepping stone to the S-tier units, as you can use these characters in your trade offers for your desired unit.
B-tier units
These units serve you well until the third or fourth Chapter of Spongebob Tower Defense, but within a couple of days of playing the game, you’re likely to secure a few of the A-tier units. With just two A-tier units with decent AoE or line damage, you won’t need to deploy anyone else on the battlefield.
C and D-tier units
It consists of most of the Common, Uncommon, and Rare units, which are some of the worst picks in the game. If you’re stuck using these units, don’t worry; you’re likely a beginner. Advance through the first two Chapters and you’ll now have enough Gems to try your luck on the summoning banners.
Additionally, make sure to use the Spongebob Tower Defense codes once you reach level 10 to get some free rewards like Magic Conches, Trait Rerolls, Treasure Chests, and Gems.
Once you have a unit that you’re likely to use for a long time, ensure you use your Trait Rerolls (next to the Summon’s area) to buff their range, damage, lower the upgrade cost, or more. For example, a rare Trait like Pursuit buffs a unit’s range by 35 percent. However, you can only roll and equip one trait for every unit.
