When you jump into the world of SpongeBob Tower Defense codes, you’ll want this guide at your side — whether you’re hunting for gems, boosters, or rare chests to help you defend Bikini Bottom with SpongeBob and friends! In this article we’ll explore what SpongeBob Tower Defense is all about, how to redeem codes and which codes are working now (or might be down). We also mention our related SpongeBob Tower Defense Script Guide, and we’ll update this post the moment new codes go live.
What Is SpongeBob Tower Defense?
SpongeBob Tower Defense, developed by Wonder Works Studio in collaboration with the publisher group Krabby Krew, is a licensed online multiplayer tower-defense game on Roblox. The game first launched on December 21, 2024.
In the game, you wander around Bikini Bottom’s iconic locations — like The Reef Retreat — and pick your first unit (such as SpongeBob, Patrick, or Squidward). Then you place towers/units, upgrade them, and fend off waves of classic enemies from the SpongeBob universe. There are different game modes: story mode (with maps and chapters), challenge modes once you reach certain levels, and even endless or survival-type gameplay.
Frequent updates (weekly or every Friday) bring new units, maps, events, crates, and — importantly — new codes that players can redeem for free rewards.
Why Are Codes Important (And What Do They Give You)?
Codes in SpongeBob Tower Defense act as freebies — they deliver bonuses like trait rerolls, pet crates, special treasure chests, gems or in-game currency, and sometimes rare or exclusive items.
Because of the game’s gacha-style and progression mechanics (summoning units, evolving them, upgrading, unlocking worlds and chapters), using codes can give you a significant early — or mid-game — boost without having to spend Robux or grind endlessly. That’s why roblox promo codes and codes in general are widely sought after by players aiming for an edge.
Codes are generally time-limited, so players need to redeem them quickly.
Active SpongeBob Tower Defense Codes
As of the most recent check (November 2025), here are some codes reported to work in SpongeBob Tower Defense:
- BFFBACK4EVER — secret treasure chest / reward
- NeedMorePets — 25 pet crates
⚠️ Some previously listed codes (on older guides) — like SERVICECRASH, KelpCityisHere, THANKYOU2025, etc. — have expired.
Because codes change, expire, or get replaced often, we keep this post updated: whenever new codes are released by the developers, we’ll add them here — so bookmark this page or check back soon!
If you try a code and it isn’t working: it may have expired, or you may need to meet certain in-game requirements (for example, some codes only work after you reach a certain level).
How To Redeem SpongeBob Tower Defense Codes
- Launch SpongeBob Tower Defense on Roblox and wait for the game to load.
- Make sure you meet any prerequisites (some codes only work if you are at least level 10 — depending on the code).
- Look for the “Codes” button (or “CODES” tab) in the game’s menu/interface.
- Enter the code exactly (caps and punctuation matter), then hit “Redeem” or “Use” to claim your reward.
- If the code is valid and unexpired — enjoy your bonus (gems, chests, pet crates, rerolls, etc.). If not — it may be expired or invalid.
