What is SpongeBob Tower Defense?

SpongeBob Tower Defense is a Roblox wave-defense game where you collect Bikini Bottom characters as units, drop them onto build spots along a fixed enemy path, and spend in-match cash to upgrade them before the waves reach your base. Every match feeds a longer collection loop: you summon new units between runs, then draw on that roster to build a stronger team for the next stage.

The game blends tower defense strategy with character collection. Story chapters hand you tuned waves and scripted boss fights, while Endless Mode keeps scaling enemies and rewards teams that cover damage, crowd control, economy, and support instead of stacking one role. Gems gate the biggest account upgrades, so farming and summoning decisions matter as much as placement inside any single run.
