The T-rex is a dinosaur who lives in the past. He is from an iPad app meant to copy human voices and change the sound to make a character on the screen to repeat it. He repeats everying Oobi says and it annoys him a lot. In the end, Caveman Charlie reveals the T-Rex is actually a time portal to the future, so if you press a button, you will go to the future. Technicly since the T-Rex copies everything Oobi says, and Oobi is portrayed by Belly, the T-Rex is portrayed by Belly.
The T-Rex is green, big and scaly. It looks like a steryotypical dinosaur. It has tiny arms and large teeth.
He only appears in Charlie's Time Machine.
- Even though this character is from the past when electricity wasn't invented, he is portrayed by an iPad app.
