Pet Simulator 99 Codes (January 24, 2026): New Secret Merch Codes and Gem Guide

Are you looking for the latest Pet Simulator 99 codes to unlock "Huge Pets" and earn millions of Gems? As of January 24, 2026, the community is hunting for new secret codes following the recent "Deep Caves" expansion. While public promo codes are extremely rare, the latest merch drops and hidden "Preston's Shop" updates have changed the game. Here is everything you need to know to boost your team today.

​The Mystery of the Super Secret Code

​Currently, the most searched term in PS99 is the "Super Secret Code" for Preston's Shop located in Area 35. While many YouTube videos claim to have found it, these codes are often player-specific or tied to physical plushies. However, Tier 1 players in the US and UK have discovered that interacting with the "Secret Tunnel" after the latest patch sometimes triggers a reward event for those with active "Merch Codes."

​How to Get More Gems and Huge Pets in January 2026

​Since public codes are limited, the best way to progress is by maximizing your daily rewards:

  1. ​Redeem Merch Codes: Every official Pet Simulator 99 plushie or toy comes with a unique, one-time-use code. These are the only codes that guarantee a "Huge Pet" or an "Exclusive Egg."
  2. ​The "Day Care" Strategy: Use the Day Care feature every 6 hours. In the 2026 update, the Gem yield has been increased by 20% for users who have completed the "Rebirth 4" milestone.
  3. ​Active Trading Plaza: Keep an eye on the Trading Plaza. Scarcity of certain eggs in late January has made "Diamond" trading more profitable than ever.

​How to Redeem Codes in PS99

  1. ​Launch Pet Simulator 99 on Roblox.
  2. ​Click on the Pet Grid icon at the bottom of the screen.
  3. ​Click on the Shopping Cart icon.
  4. ​Scroll to the very bottom of the Shop menu until you see the "Redeem Codes" banner.
  5. ​Click Redeem, enter your code, and claim your rewards instantly!
