Welcome to Bikini Bottom, where jellyfish sting, Krabby Patties sizzle, and tower defense just got a cartoon twist. SpongeBob Tower Defense isn't just another Roblox game—it’s a nostalgia-loaded battleground, where you team up with fan-favorite characters to fend off waves of foes with sharp strategy and a bit of nautical nonsense. And if you’re here, you know one thing: codes matter.

Those redeem codes are more than freebies—they’re boosters, lifelines, and sometimes, golden tickets to the next big win. Whether you’re short on Gems, itching for Magic Conches, or just want to level up faster than Plankton can hatch a plan, this guide has you covered.

As of now, here are the working codes in SpongeBob Tower Defense you should cash in without delay:

• THANKSFORSUPPORTING – Grants 5,000 Gems, 50 Magic Conches, and 10 Epic+ Chests

• 500KFeelingOkay – Gives 2,000 Gems, 10 Rare+ Chests, and 1 Magic Conch

These aren’t your everyday rewards—they can set you up for some serious squad upgrades. New players get a jumpstart. Veterans? You know the drill—more resources, more experiments, more fun.

Before you start copy-pasting, there’s one thing you need to know: you must be Level 10 to unlock code redemption. It’s a clever gatekeeping move by the devs that ensures you’re invested before they hand you the keys to the vault.

Once you hit Level 10, follow these steps:

1. Launch the game and enter a server.

2. Look for the clam shell icon labeled “Codes” on the left side of your screen.

3. Click it. A box will pop up.

4. Paste your code in the text field.

5. Hit “Enter” and—boom—rewards inbound.

Be exact. Codes are case-sensitive. Typos will leave you empty-handed.

These expired codes were fan-favorites and could return in a future event or milestone. Don’t count them out just yet:

• DoubleIt – Offered Double XP, Double Gems, and Double Coins boosts

• TheHuntBegins – Delivered 15 Chests and 5 Golden Trait Rerolls

• 1MillionLikesOP – Included 10,000 Gems, 25 Magic Conches, and 15 Rare Chests

If you’re new here, take these as clues. The devs love theme codes tied to community milestones, events, and seasonal celebrations. So when the next holiday rolls around—or that player count ticks upward—you’ll know what to expect.

Let’s break it down:

• Gems : In-game currency used to buy units, reroll traits, or open packs.

• Magic Conches : Special items often tied to premium rewards.

• Chests : These range from Rare+ to Epic+, containing character upgrades, traits, and sometimes entire new towers.

These rewards aren’t just cosmetic. They directly impact your defense strategy, your character build, and your ability to push into harder maps and late waves.

Want to be the first to know when new codes drop? Here’s the playbook:

• Follow the Game Developers : Updates usually appear on the game's Roblox page or via announcements in the in-game menu.

• Join Community Servers : Discord groups or forums can be treasure troves of leaks and early releases.

• Keep Track of Milestones : Codes often pop up at major player count achievements or seasonal events. Think holidays, game anniversaries, or huge updates.

Being early isn’t just fun—it’s smart. Some codes are limited-time and vanish before most players even find out.

Aside from its iconic setting and familiar characters, this game rewards experimentation. The right unit placement, clever trait use, and timing can make or break a round. That’s why those Epic+ Chests from codes are such a game-changer.

You’re not just grinding. You’re building a defense dream team—one Krabby Patty-loving guardian at a time.

Gems: Currency used across nearly every mechanic

Magic Conches: Rare items used in premium systems

Chests: Open for new units, traits, and boosts

XP Boosts: Help you level up your account and access tougher stages

Trait Rerolls: Essential if you're min-maxing your favorite towers

In SpongeBob Tower Defense, every edge counts. Whether you're fending off another wave or prepping for a high-difficulty run, the right code at the right time can change everything. Think of them as tactical boosts hidden in plain sight.

Check back often. Test every code. Because down here in Bikini Bottom, the smartest players aren’t just good at tower defense—they’re good at timing.

And in case you needed a reminder: don’t keep this info to yourself. Share the knowledge. Share the codes. Let your squad know.

Your next Epic+ drop could be a code away.
