Update 19 of SpongeBob Tower Defense has finally dropped, bringing with it a huge new event called Dudes and Dragons. One of the highlights of this update is the arrival of Sir SpongeBob, a brand new limited-time unit that players can only get during the event period. If you’re wondering how to unlock this exclusive character before time runs out, this guide will walk you through the full process.
Who Is Sir SpongeBob?
Sir SpongeBob is one of the eight new units added in Update 19, themed around knights, dragons, and fantasy. Unlike regular units, Sir SpongeBob is a limited unit, which means:
- He can only be unlocked during the 10-day Dudes and Dragons event.
- After the event ends, he won’t return—at least not anytime soon.
- His rarity and power level make him one of the most valuable additions to your collection.
Step-by-Step Guide to Unlock Sir SpongeBob
1. Play the Dunes Dragons Raid
To begin the process, you need to play the Dunes Dragons Raid Map—a brand new permanent map added in this update.
- This map drops a special event currency called Dragon Scales.
- Dragon Scales are only available for 10 days, during the event period.
- The more you play and win in this raid, the more Dragon Scales you earn.
2. Collect Enough Dragon Scales
You’ll need to farm Dragon Scales through repeated runs of the Dunes Dragons raid.
- Play in a full party to get up to 50% more currency thanks to the new Party System.
- Consider using your best units or joining with higher-level players to complete raids faster.
3. Open the Dragon Crate
Once you’ve collected enough Dragon Scales, head over to the event shop or crate area and spend your currency on the Dragon Crate.
- The Dragon Crate contains seven of the eight new limited-time units.
- Sir SpongeBob is one of the units in this crate, so you’ll need to open crates until you get him.
Tip: The Dragon Crate works similarly to a gacha system, so the drop is random. It might take several tries to unlock Sir SpongeBob.
4. Keep an Eye on Bonus Codes (Optional)
While there hasn’t been a confirmed code specifically for Sir SpongeBob, the developers sometimes release limited-time codes during update weekends. These codes might give you:
- Free Dragon Scales
- Boosts or buffs
- Extra summons
Check the official YouTube channel or Discord server for any active codes during the event, or if you didn’t want to check you can just use our Spongebob Tower Defense Codes to make it easier!
Sir SpongeBob is a must-have limited unit from the Dudes and Dragons event in SpongeBob Tower Defense Update 19. By grinding the Dunes Dragons Raid, collecting Dragon Scales, and opening Dragon Crates, you have a chance to unlock him—but only for a short time. Whether you want him for his power or just to complete your collection, this is one opportunity you won’t want to miss. Are you planning to grind for Sir SpongeBob right away, or are you saving your Dragon Scales for something else?
