Set in Flossmore Valley and Egypt, Timmy, Brushbrush and Bubbles visit the pyramids on their official pyramid investigation business as they explore the pyramid of King Tooth Uncommon.

During a rainy day, Timmy imagines that he is Captain Good Guy, and Brushbrush is his first mate. They work to save Sunny the Sun 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.
