Frequently Asked Questions (FAQs)
Fat Potions are premium items that provide an instant weight boost to your character. Instead of having to click or eat food items manually to grow, consuming a Fat Potion gives you a significant amount of mass immediately, allowing you to create much larger splashes and earn more currency.
If a code isn’t working, it is likely due to one of two reasons:
Case Sensitivity: Codes must be entered exactly as shown (often in ALL CAPS).
Expiration: While there are no expired codes currently, developers can deactivate them at any time without notice.
One-Time Use: Most codes can only be redeemed once per Roblox account.
Sometimes developers hide codes in the game environment or release them through specific Roblox influencers. However, the most reliable codes are the ones officially released in the Shop menu as listed above.
New codes are typically released when the game reaches a major milestone (such as 50,000 likes) or when a new seasonal update is launched. Be sure to “Like” the game to help reach those milestones faster!
