Born and raised in Happyville, a small funny-farming community in the not-so-plain regions of Cuteopia, Snuzzy started collecting cute and fuzzy pet-related things way back when he himself was still very cute. And slightly fuzzy. His collection of all things cute and fuzzy eventually outgrew his cute and fuzzy warehouse, causing a Loony-Tunes-like explosion of cuteness and fuzziness that sent clouds of contagious laughter throughout Cuteopia. Too much cuteness for even a place called Cuteopia to handle, Snuzzy expanded his cute and fuzzy operations and moved to Cyberspace, where he lives today. Snuzzy sails a silly little boat called Snuzzy: Where Cute and Fuzzy Collide, and occasionally writes under the pseudonym Schmanders Schmorter.
