Simon the rabbit is one of the two main characters and (half of) the namesake of the show. Being more plucky and spontaneous when compared to his buddy Grimpus, Simon dreams of a career on the silver screen. He idolizes celebrities such as Dav Pickle, and wishes to be like them. Some may view him as loud and obnoxious, but he is simply an outgoing, sociable, and happy-go-lucky little rabbit in a big world! He is always seeking friends and is immensely loyal to them, especially Grimpus.

The pair take on strange jobs in order to gain popularity and experience towards Simon’s acting career. Grimpus, while being a reluctant companion to these adventures, views Simon as an invaluable friend. The two will forever stick to each other, no matter what! After all, the two don’t harbor any grudges or secrets!
