SpongeBob Tower Defense Codes (December 2025) – Working and Expired

If you’ve ever wanted to build your dream team of SpongeBob characters and defend Bikini Bottom, SpongeBob Tower Defense makes that possible and a bit chaotic. But here’s the catch: it’s a grind-heavy game, and pulling top units or getting enough loot takes time. That’s where codes come in.

The developers regularly drop codes that give you free rewards like Mythic Chests, Gold Trait Rerolls, and Secret Treasure Chests. And if you’re level 10 or above, you can redeem these codes and boost your game instantly.

Let’s walk through all the currently active codes, how to redeem them, where to find more, and a few extra things you should know about the game.

All Working SpongeBob Tower Defense Codes

These are the latest active codes, confirmed to work as of mid-December. Some give massive chest bundles while others offer rare crate drops or rerolls:

These codes are time-limited and may expire soon, so it’s best to redeem them quickly.

Are There Expired SpongeBob Tower Defense Codes?

Yes, tons. The game has received over 100 codes since launch, and most are no longer active. These include popular ones like:

• THANKYOU2025
• GOODLUCKATTHERIA
• EXOTICCHESTPLS
• ADOPTASPONGEBOB
• UPD22CHESTSPLS
• GIVEMEDRAGONCAPSULES
• SLEEPYPATRICK
• IMREADYIMREADY
• MASSIVEUPDATEISMASSIVE
• and many more

These won’t work anymore, but can show you how frequently codes drop — especially around milestones and events.

How to Redeem Codes in SpongeBob Tower Defense

Redeeming codes isn’t available right away. You need to reach Level 10 in the game first. This encourages players to experience the game before collecting free loot.

Once you’re Level 10, here’s how to use the codes:

1. Open SpongeBob Tower Defense on Roblox.
2. Click the Shop tab on the left.
   
3. In the shop menu, press the Codes option.
4. Enter the code exactly as shown (they’re case-sensitive).
5. Hit Redeem and enjoy your freebies.
   

If you enter a code with a typo, it won’t work; you’ll get an “Invalid Code” message. Best to copy-paste directly.

Where to Find More SpongeBob Tower Defense Codes

There’s no strict schedule for new codes, but here are a few places where developers drop them:

• WonderWorksRB on Twitter/X.
• The official Krabby Krew Roblox Group.
• The Krabby Krew Discord server, where codes are sometimes shared during events and patch drops.

Quick Tip: What Makes These Codes Valuable?

If you’re new to the game, here’s why these codes matter:

• Secret Treasure Chests can contain rare or exclusive units.
• Mythic Chests offer better odds in the gacha system.
• Gold Trait Rerolls let you re-roll unit traits to optimize performance.
• Magic Conches and Exotic Chests are premium items not easy to grind.

Using these codes can save hours of farming, especially helpful if you’re trying to get stronger units or build a top-tier team faster.

Bonus: What Are the Rarest Units in the Game?

There’s no official single “rarest” unit, but the S+ tier units are the hardest to pull and usually have the best stats. Some examples include:

• Dream Gary
• GG Rock SpongeBob
• Cyborg Plankton
• SpongeGar
• The Quickster
• Captain Magma
• Sea Bear
• Smitty Werbenjägermanjensen

These are extremely low drop-rate units, so save your best chests and rerolls for chances to get them.

Is SpongeBob Tower Defense Official?

Yes, this game is officially licensed and developed in partnership with the owners of the SpongeBob IP. That means all your favorite characters, from SpongeBob to Sandy to Patrick, are legit and legally used in-game. It’s not a fan-made copy; it’s the real deal.

If you’re ready to start building your Bikini Bottom dream team, don’t wait too long, these codes can expire at any time. Bookmark this page or check back weekly for the latest updates.
