Hamster Valley is a town with a magic in it. This magic causes anyone who steps foot into the valley to be afflicted. This magic is not at all noticable inside the town, as its effects only apply whenever leaving town. The spell turns anyone who enters the town into hamsters, but this is undetectable as it also grants them a human disguise that applies when in town. However, when they leave the town, their disguise will wear off until they step back into the town, and they'll turn into a hamster
