When you want to adventure deep underwater and explore Bikini Bottom, you might want to gear up first. Because having some top-tier units is key to defeating the waves of enemies, and the SpongeBob Tower Defense tier list ranks each one!

The whole point of SpongeBob Tower Defense, which admittedly is one of my favourite Roblox experiences (right up there next to Dress to Impress and Adopt Me), is to deploy units that attack the enemies in order to defend your base. Each level has its own unique layout that enemies follow, and if you want to annihilate them before losing all your life, you need to think carefully about each unit's placement. 

You can level up the characters, equip them with unique Traits and even fuse them - but that's not all. Since you want to have the highest chances possible at passing all the levels (or as many as possible in Endless mode), you want to deploy your best. Which are the best? That's what you will discover in the following pages. 

Best units in the game

From secret units to Mythics and lower, SpongeBob Tower Defense tier list compares each one and ranks them accordingly. Be it a limited edition of SpongeBob or an exclusive Squidward, you can find exactly which ones you should try to have on your roster.

Since you can have up to 6 units (based on your level), I recommend you always try to use the ones that are sitting in the highest tiers. That is, if you have them, of course.

And without further ado, let's dive into the SpongeBob Tower Defense tier list!

Handsome Squidward is just a fabulous unit. His attack is AoE, allowing him to hit multiple enemies. Furthermore, it has some CC in the form of Slow, which will help you slow down the enemies he's attacking and thus the wave.

GG Rock SpongeBob is really cool - he plays his guitar and shoots a blue ray at enemies, which basically obliterates everyone. His attack is super high and he is one of the best out there in terms of damage.

Captain Magma is a variation of Squidward, which is insane in terms of pure, flaming damage. Quite literally. He shoots a firebeam at enemies, similar in a way to GG Rock SpongeBob, but it's a lot deadlier (in my experience).

A tier

King Neptune Mythic
Patty Obsessed Squidward Epic
Texas Sandy Epic
Atomic Flounder Epic
Miss Appear Legendary
Mermaid Man SpongeBob Epic
Flying Dutchman Legendary
Man Ray Mythic
Pearl Rare
Larry The Lobster Epic
Grandma SquarePants Rare

King Neptune is a good unit that has AoE attacks that can affect a designated spot. His area of attack is pretty high, so it's good to place him in the corners for maximum damage output.

Soaring Starfish is the only Limited unit available right now, and he has kind of a unique style. He can be placed above the enemy path and he will drop chocolate bombs at the enemies that walk underneath.

Mermaid Man SpongeBob is decent, but he feels like the lesser version of Captain Magma. He fires a water beam at the enemies and deals AoE damage to the units in the area.

B tier

Dirty Bubble Epic
DoodleBob Legendary
Barnacle Boy Patrick Uncommon

Barnacle Boy Patrick is the one unit that carried me through the first 10 levels with ease. He has decent attack speed and when he reaches level 5, he will be a reliable unit to deploy multiple times.

Elastic Waistband is also not that great - he is another version of Patrick, and he can be placed around corners for maximum damage output. Basically, he spins and deals damage to the enemies in the area.

At the bottom of the SpongeBob Tower Defense tier list, we have units that are not that good in the grand scheme of things. You can use them (if you get them) at the very start, mainly for Act 1, but other than that, it's best you try to obtain the units that are ranked in the A tier or S tier. These ones lack a lot of attack and attack speed, so later on, you won't be able to keep up with killing all the enemy waves.

We're covering other Roblox titles pretty seriously - just take a look at the Volleyball Legends tier list, for example, or the Verse Piece race tier list and you'll know what races are great to pick.
