- "T. Rex" is not to be confused with Rex or Tyrannosaurus rex.
T. Rex is a ground pangolin, whom the Wild Kratts meet in the episode "Pangolin Rescue". While collecting keratin scans from different animals, they notice a pangolin walking by and Aviva has never seen anything like it before. Seeing how it walked on two legs with its arms and claws out like a T. rex, Martin decided to name it T. Rex, in honor of one of the most famous dinosaurs of all time. Suddenly two lionesses appear and T. Rex rolls himself into a ball to protect himself. Sometime later when the Wild Kratts head off to China to rescue pangolins being trapped by Gourmand, Chris gets captured by him and sees that Gourmand had already taken T. Rex along with several other pangolins. Luckily with the help of Martin, T. Rex, Artichoke's mom, and the other pangolins are set free as they roll into the ocean and swim away.
