Gregory's Little Friend was Greg's virtual pet chihuahua on Net Kritterz. He loves his virtual dog and constantly takes care of it, but dislikes its name, which was chosen by Susan. Greg asks for Kritterz Kash to buy a jacuzzi for his pet. After Manny plays Net Kritterz and changes the password, and blowing everything Greg ever earned in the Kritterz Kasino, Greg receives emails from Net Kritterz that Gregory's Little Friend misses him, and Greg "doesn't think my [his] chihuahua is gonna make it." Gregory's Little Friend only was in Cabin Fever.
