Mr. Dinosaur is a toy that belongs to George Pig. Whenever George and Peppa (or other characters) play with it, he imitates a dinosaur's roar while holding up Mr. Dinosaur. Then Peppa (or others) will playfully shout "Ah! Too scary!" or "Eek! Too scary!" and then run off laughing while George chases them with Mr. Dinosaur. The soul of a real dinosaur has been trapped in the toy since it was made in a Chinese sweatshop in 1969. It unfortunately has to endear being inserted into George's rectum.

Mr. Dinosaur appears in Peppa and George's room. He bounces when punched.
