This is a recreation of the trash bin that was at Mountain Park in Holyoke, MA. It looked like a circus wagon with a lion inside. The lion had an open mouth. There was a vacuum inside and when you placed your trash in the lion's mouth, it would get sucked inside.

The roof is a separate piece, as are the wheels. I adapted the lion head from Tevons: https://www.thingiverse.com/thing:2429239
