.. Return Lloyd's gerbil

Search the house. It is a rodent, after all, and will stick itself in all kinds of places.

Scritch, scratch...

It is in the fireplace. After you get it out catch it.

You are not allowed to open his door. So there's no way from inside the house.

First, get out of the house. Maybe there's a way to Lloyd's room.

Look at the broken window. That is Lloyd's room. Is there a way to get there?

Put the gerbil into the drain pipe at the right of the house. Lloyd will throw Mr. Fumbles down.
