In this episode, the animals fear that they will be returned to their feral, uncivilised state. Zoe is torn between her desire to help and her need to return home.

Alex and Zoe go on a search for a Corespore in a place where lost Animalian memories go, Memory Canyon.

The Creeper sabotages the Core by destroying a main root which causes the animals to revert to their original language. The kids must find the origin spore that allows the animals to communicate.
