What Is SpongeBob Tower Defense?
SpongeBob Tower Defense is a Roblox strategy game featuring the world's most famous sponge and his ragtag group of friends as the characters. In this tower defense experience, you'll place SpongeBob, Patrick, Squidward, and other Bikini Bottom residents as defensive units to stop waves of enemies from reaching the Krusty Krab.
Gameplay-wise, the experience follows all the usual formulas of the genre. You'll need to summon and upgrade your units to strengthen them enough to endure the harshest levels. The game features a gacha summoning system where gems let you roll for rare characters, while treasure chests guarantee powerful units for your defensive lineup. Can you complete the story mode and save Bikini Bottom from the intruders?
Game Features:
- 50+ SpongeBob characters to collect
- Multiple difficulty modes and endless waves
- Pet system for additional bonuses
- Regular updates with new characters and events
