Gustavo makes his playable debut in Gnome Forest where he drops off Gnome Pizzas to many gnomes throughout the level before the former freezes up. He can be seen throughout the game, guiding Peppino towards the exit in most levels and appearing on every floor in the Hub developing a relationship with a Stupid Rat, later named "Brick". He first appears outside in the game’s opening, looking at a map until he is run into by Peppino. In McPig's words, "Gustavo is super friendly, but don't disappoint him, he'll get back at you." This is shown when you fail to deliver pizza in an earlier build, as he would show his dark side and pummel Peppino as an act of punishment.

He is generally shown to be a nice person who likes to help others, but he has also been shown to get angry at times. He also wears a chef's hat, brown pants and shoes. He wears a brown shirt and a white apron. Gustavo is a small man with beady eyes, a big nose, brown hair, and a brown moustache.
