The Animal Within

CGI animated series. Alex and Zoe stumble upon a magic portal in the library and are transported to the world of Animalia, where animals can talk.

When Alex and Zoe share a meal with the Horrible Hogs at the Elephants' Eatery they're appalled by the Hogs' awful table manners, crudeness, and limited social skills. The Hoity-Toity toucan overhears, and puts a spell on Alex and Zoe, making them Neanderthal versions of themselves.
