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 unknown how Manny changed the password without knowing the original one, as most sites require also the original password to make a new one.
- It is based on many virtual pet games on the web, most notably Neopets and Webkinz.
- The fact that buying Kritterz Kash with real money is vital is a reference to many video games that require real money to progress such as Roblox (Robux) and Neopets (Neocash)
- It takes a long time to earn or you must buy it could be a reference to Roblox's 2 currencies Tix (the currency you earn. also RIP tix) and Robux (you could only buy this)
- It is also similar to Animal Jam as Manny traded items for Kritterz Kash. However, you can't trade for currency in Animal Jam.
