Here is a quick drawing for you home haunters. It uses a garbage can that has wheels in the back. I picked those can because they are larger but I think you would make this work with small cans too with or without the wheels.

In the picture a guy pushes a monster in a garbage container. The monster comes to life when around people.

The can is rigged with a hole in the back and a slanted platform inside made of plywood. There is an extra 2 front wheels hidden by a strip of black rubber that need to be installed.
The top half of the guy pushing is fake. Its just a costume over chicken wire. The head is just a mask. Arms and hands are fake as well.
The legs are real and the actor is inside laying on the plywood dressed like a zombie.
