Fantastic Max is a cartoon about a 16-month-old boy and his travels through space on adventures. His colleagues are FX, a green alien from the planet Twinkle Twinkle, and A.B. Sitter, the butler/companion he constructed from his toy blocks. His older sister, Zoey, is often oblivious to his other life as an intergalactic hero, but often gets caught up in sticky situations. It's up to Max to save the galaxy before his naptime.
