Spongebob Tower Defense on Roblox just dropped a fresh event—and this one’s packed with limited-time rewards.

What is Secret Agent Star?

Secret Agent Star is a special limited-time unit introduced in a four-week event. He’s not just another cosmetic—this guy is locked behind a full mission chain spread out across several weeks. You’ll need to complete a total of 12 missions (3 each week) to unlock him, and there’s a limited mount you can also get halfway through the event.

Operation Krabby Code: How the Event Works

The event is called Operation Krabby Code, and it’s a four-week campaign with a storyline tied to Star’s secret missions. Each week unlocks 3 new missions:

• Mission 1 unlocks every Tuesday
• Mission 2 unlocks every Wednesday
• Mission 3 unlocks every Thursday

You don’t have to log in exactly on those days. Even if you miss them during the week, all three missions stay available for the entire week. That means you can still catch up during the weekend.

Week 1 – How to Complete the First Mission

The first mission is pretty straightforward:

• Objective: Collect 5 Sabotage Schematics from the Chum Bucket.
• Where: Go to the bus and teleport to the Chum Bucket.
• Drop Rate: 50% chance per run.
• Game Mode: Works in both Normal and Hard.
• Chapters: Any chapter drops the item.

Expect to run the mode around 5 to 10 times to get all five items. Once you collect them, the mission is complete, and you’ll earn 2,000 gems as a reward. Then, you can unlock the next mission the following day or move on immediately if you’re catching up later in the week.

Week 2-4: Upcoming

• More will be updated here!

Secret Agent Star isn’t just a cool new unit—he’s a reward for players who stick with the missions and keep up weekly. The mount and bonus gems make the grind worth it, and the missions are casual enough to finish over a few days. Make sure you complete each week’s set of missions in Spongebob Tower Defense before the next one unlocks, and you’ll be on track for all rewards. Now’s the time to join the Krabby Code and save Bikini Bottom. Just don’t miss your daily drops—and keep your eyes peeled for that Rock Bottom update coming soon.
