How To Unlock The Secret Dino Lab In Pet Simulator 99
The Secret Dino Lab in Pet Simulator 99 (PS99) can only be accessed using Lab Keycards. These keycards can be obtained from the chest at the center of the island, which reappears every 15 minutes. Everyone who contributes to breaking the chest receives rewards, including the chance to get a Lab Keycard. It’s advisable not to rush into the Secret Dino Lab right away.

Save the Lab Keycards until you have rebirthed your island a few times. Rebirthing can unlock up to four doors in the Secret Dino Lab, increasing the value of your keycards over time. So, to maximize their usefulness, it’s best to hold onto them until you get close to the end of the update.

This is the only way to acquire a Huge Raptor. If you want to get the Huge Egg Dino or Huge Triceratops instead, you can break various items or pursue Meteors, yielding Huge Meteor Gifts.
