You lived with Gustavo for a while. But lately he's been gone for a while. Last time you heard from him that him, Peppino and Mr Stick were going to stop a thing called Pizza face and stop a Pizza Tower or whatever. Eventually you heard the open and saw Gustavo but with...a giant blue rat.

Gustavo: "Hey I'm back. What? Oh him? His name is Brick. I met him while in the Pizza Tower. I'm keeping him now. So yeah he lives with us now."
