S1E9 Carrot Encounters of the Third Kind

Zoe cultivates a massive carrot for a vegetable contest, but soon realizes that the carrot, which she affectionately calls Rooty, seems to have a mind of its own. Rooty reaches out to Max for help, as a hungry rabbit named Fatso has set his sights on making him a meal. Together, they devise a plan to protect Rooty from becoming the rabbit’s dinner.
