Walter the Watermelon Robot
In Episode 2 of Baking Impossible, Cindy and I build an obstiable-cource navigation robot built primarily inside the shell of a watermelon. Our decor was entirely edible, and only electro-mechanical parts like motors were made of traditional electronic materials.
Walter featured an animatronic music routine where he cried, changed facial expresson, and sang a custom song (vocals by Cindy), though this footage never made it to streaming.
