Oscar's Hotel for Fantastical Creatures

The Fountain of Forgetfulness (1x4)

:

Afflicted with a nasty case of amnesia, the only thing Oliver can remember is that he’s on a mission to save the hotel. He finds assistance with a new friend, the Hermit, who lives in a cave deep within the hotel’s Fountain of Forgetfulness. But there’s only one problem -- he can’t remember how to save the hotel, or anything else. He searches for clues, and as he does… things soon take a dark turn with the seemingly innocent Hermit.
