SpongeBob Tower Defense just dropped one of the most powerful limited units we’ve ever seen in the game, and if you haven’t heard yet — The Moth is here. But this isn’t just another new unit. This one might actually rival secrets in terms of performance. In this guide, we’re breaking down how to unlock The Moth, what it can really do in battle, and why it might just be the best limited unit in the game.

How to Unlock The Moth in SpongeBob Tower Defense

The Moth is tied to the new Operation Evil limited-time event. This event runs across four weeks, and each week includes nine quests — three on Tuesday, Wednesday, and Thursday. Here’s how it works:

  • Complete 3 quests per day (Tuesday–Thursday)
  • Earn individual rewards for each quest
  • Unlock milestone rewards by finishing all nine quests each week

To get The Moth, you’ll need to complete all 36 quests across the event’s full duration. Along the way, you’ll also receive:

  • A Secret Chest
  • The Invisible Boatmobile Mount
  • A Boosted Secret Chest

Only after completing all 36 quests will you receive The Moth, making it a true endgame reward.


Base Stats: Is The Moth Any Good?

At level 1, The Moth already looks dangerous:

  • 5,200 damage
  • 1.3s cooldown
  • 22 range
  • Line attack type

Even without any traits, stars, or upgrades, this limited unit performs like a top-tier mythic. But once leveled up, things get serious:

At max upgrade (still no traits or stars):

  • 13,000+ damage
  • 1.1s cooldown
  • 33 range

And yes, you can place three of them in a game.


Performance Breakdown: Mythic or Secret?

Testing began with just one Moth on the field, and it effortlessly cruised through Wave 197 — the baseline for calling any unit a decent mythic. But the real test came when all three Moths were placed. The results? Shocking:

  • Reached Wave 266 with two Moths (making it better than all mythics)
  • Pushed all the way to Wave 294 with three Moths placed
  • That puts The Moth in an exclusive “in-between” status — not quite a secret unit, but stronger than any mythic or legendary

Right now, there are almost no units that survive in this wave range unless they’re secret class. That means The Moth is officially the most powerful limited unit in SpongeBob Tower Defense and a top-tier tower overall.


Is It Worth the Grind?

Absolutely. Let’s break it down:

  • 36 quests across 4 weeks
  • Multiple milestone rewards along the way
  • A limited unit that outperforms every mythic and legendary in the game

If you’re into late-wave pushing or want a unit that could give secrets a run for their money, this is it. The Moth isn’t just a cool reward — it’s game-breaking in the best possible way.


The Moth has set a new standard for limited units in SpongeBob Tower Defense. It’s not just strong — it’s borderline secret-tier. If you’re serious about climbing higher and crushing waves, this unit is a must-have. The grind may be long, but the payoff is absolutely worth it. Get those quests done, and lock in one of the best units the game has ever released. Stay tuned for more updates — especially with crafting coming soon.
