Net Kritterz is an online-virtual pet game that Greg has been playing ever since he lost his doll Alfrendo. Greg's pet's name is Gregory's Little Friend. In the game you have to do things to make your pet happy and it also costs real money to buy some items. However, Susan doesn't like it because Greg keeps asking her for money for his pet. One day, Greg's account got locked by Manny because Manny sneaked into his account and changed the password. It is based on many of the virtual pet games on the net.
