So I'm putting together a VTM game for some friends. I was telling my wife about it last night. She wants to be a random chance pooka prankster that messes with them occasionally. Advice?

I'm totally down for it. At first she wanted to be a traditional fairy that guards her flowers and plays pranks on them or something but from what I can tell that isn't really a thing. The closest being a pooka. Best way to integrate this? She just wants to take their car keys and replace them with the 7/11 bathroom keys. Stuff like that lol
