Oh thank you. I guess I'm just having one of those moment... Either I'm too creative or not creative enough to find the correct solution.
I tried using a brick to smash the can.
I tried using the bus sign with the can.
I tried using a stone with the book.
I tried to lift the sofa with a stone to look under the cushion for something.
I also picked up a skull but it disappears from my inventory when I pick it up.
