Wally O'Wisp
Wally O'Wisp is an NPC who appears in the The Sims: Makin' Magic Expansion Pack.
When a Sim uses the 'Of House and Home' charm, Wally will appear and will clean the Sim's home and fix broken items. After some time, he will disappear. However, if the sim who used the charm is in a bad mood, Wally's sister Molly will appear instead and will break items in the household.
Wally does not have any face or body, instead only his clothes and cleaning items are seen. Some stars will appear next to Wally when he is on the home lot.
