Creepy-Crawler Condos Build a beauteous bugopolis. This Bug Podz Habitat Construction Kit for homeless insects is modular. Made mostly of clear plastic, it comes with (4) pods ready to be furnished with dirt and foliage (one of which has a "capture port" for use with a bug vacuum) plus (6) corner pieces, (4) 8" long tubes and (8) 4" long tubes (think apartment hallways), (24) connectors, and a dozen end-caps. You add the critters with the help of a 28-page field guide. Interchangeable parts mean you can get multiple sets and construct an insectacity. And remember: bugs are free, gerbils cost money. For ages 5 and up.
