Willygigs are a mysterious race of time-traveling beings about whom next to nothing is known. At the moment, the Mansion is home to only one, whose name is Protus. They appear to have the ability to travel back and forth in time freely(E). Willygigs often have trouble reconciling their personal time-stream with those of the the people they talk to, frequently referring to events that have not happened yet for their interlocutor.

They appear to be vaguely reptilian humanoids with a cloud-like, tentacled lower body. They have two arms with thumbs, hair, and wear "dorky techno-nerd sunglasses." Protus wears a tool belt.

Protus is mentioned(E) in Arthur's report to Yasmine.
