You could also make some ghosts, mummies, and a tiny Frankenstein with cut wooden dowel rods painted with hamster safe paints. You could make a two-story, spooky, haunted house out of popsicle sticks that are painted with hamster safe paints. The haunted house can be created so Wasabi can go inside and thoroughly enjoy both levels of it, too. You can also use some extra gnarly grapevines to create a haunted forest complete with a popsicle stick coffin and tombstones. I think the sky's the limit to all the awesome things you can create to make the Halloween themed cage extra awesome for you little one to enjoy. I look forward to seeing what do with it so please post pics if you have a chance. Have tons of fun with it and just let your imagination take over.
