The Critter Squad Wildlife Defenders solves the one problem that a majority of kid's parties face: a lack of chinchillas. The expert handlers roll up to celebrations with reptiles, bugs, cute mammals, or an eclectic mix—their menagerie includes almost 30 species, and runs the gamut from Cochita, a Brazilian short-tail opossum, to Long John, a Burmese python. The animals are all very tame, so kids can pet their new friends fearlessly under the handler's supervision.
