Timmy finds his old toy rocket and imagines that he and Brushbrush are astronauts in space. They head to Planet Shmengee to liberate the space station from the Cavity Goon and Miss Sweety.

This show was about the adventures of a talking tooth named Timmy and all his friends of Flossmore Valley as they go on adventures using their imaginations, which would usually have Timmy thwarting bad guys like the Cavity Goon and Miss Sweetie or the Gingivitis Gang.
