Normal kids build dioramas for History assignments. Squidge Dibley builds a time machine. When class 6PU's pet, Bubble O'Gill, accidentally falls into its wormhole and gets lost in time, it's up to the stretchy, bendy kid with ultrasonic burps to rescue him before he dries out and/or destroys life as we know it. Along the way, Squidge encounters some of the weirdest, wildest people and events from history, and leaves each place he visits just a little bit squidgier.
