SpongeBob Tower Defense has found its place on Roblox, giving fans of the classic Nickelodeon show a colorful tower defense adventure. In the game, players team up with characters like SpongeBob, Patrick, and Squidward to protect Bikini Bottom from waves of wacky enemies.
But winning battles takes more than just good strategy—it also takes resources. That’s where codes come in. They’re one of the best ways to grab free boosts, gems, and special items to help make your team stronger.
All Working SpongeBob Tower Defense Codes (June 2025)
As of the latest update (June 28, 2025), there aren’t many active codes left because lots of older ones have expired. Still, there’s at least one code you can use right now:
- ThatsAlotofChests: Redeem this for 20x Treasure Chests (NEW)
Earlier this month, these codes were working but have since expired:
- WereSoBackSBTD – Redeemed 5 Mythic Treasure Chests and 5 Challenge Crates
- FreeExoticYay – Redeemed 14 Super Goo and a 2× Sand Dollars Boost
Note: Codes can stop working at any time, so always check they’re still valid before trying to redeem them.

WPatchChatMany of these codes gave out rewards like:
- Mythic Treasure Chests
- Challenge Crates
- Gems
- Sand Dollars boosts
- Skins or character upgrades
It’s worth keeping track of old codes because sometimes the developers bring back old rewards or make new codes with similar prizes during updates.
How to Claim Your Free Rewards
Unlike some Roblox games, SpongeBob Tower Defense won’t let you use codes until you reach Level 10. So if you’re just starting out, focus on leveling up first.
Once you’re Level 10, here’s how to redeem your codes:
- Open the game: Launch SpongeBob Tower Defense on Roblox.
- Go to the Codes menu: Click the small clam shell icon on the left side of the screen. This opens the code window.
- Enter the code: Type or paste your code into the “Enter Code Here” box.
- Redeem it: Click the Redeem button. If the code works, your reward shows up above the box. If it’s expired or typed wrong, you’ll see “Invalid Code.”
Why Isn’t My SpongeBob Tower Defense Code Working?
If your code isn’t working, here are a few reasons why:
- The code might be expired. Some codes only last for a short time.
- You might not be Level 10 yet. You can’t use codes until you level up enough.
- Typos. Even one wrong letter or extra space can break the code.
- Temporary issues. Sometimes the game has server problems. Wait a bit and try again.
If none of these help, check the game’s community channels for updates on which codes are working.
