The starter Hopper Hideaway set here includes two houses and one tunnel (as pictured above); you can purchase additional houses and tunnels separately to make a larger play toy for your furry friend. Make a long straight line down a hallway, a fort, or a maze through the bunny room. The only limitation is your imagination! See pictures below for some ideas.
The Hopper Hideaway is shipped flat, and assembly takes just a few minutes.
