.. Finding proof that Fud Funnie drew on walls

Start from his room. ( Room 8 )

Anything suspicious. ( Look at the gum on top of the toilet. )

A peeping hole! Look into the hole. Now you just need to get Fud caught.

Go talk to Fud and use the beeper decoy.

He is probably peeping into Ginger's room. Room 7.

Go into the room 7. Look at the portrait in the bathroom. You caught him! Go talk to him in front of room 8.
