Life as a mouse isn't half bad, it turns out. To our narrator's surprise, he can still talk (in his own human voice). Plus, mice don't have to worry about a lot of the things little boys do (like school and people not liking them).
Most importantly, he's pretty sure his Grandmamma will love him, no matter who, or what, he is.
He starts to look for Bruno, the other boy who was turned into a mouse. The narrator finds him nibbling away on some food – surprise, surprise.
Bruno, not the sharpest tool in the shed, doesn't even realize he's a mouse, and our narrator has to be the one to break the news. Once he does, he's also able to convince Bruno that it's not a bad life – at the very least, he can definitely keep eating.
Our narrator asks Bruno how he thinks his parents will react. Bruno knows his mom hates mice, and his dad certainly won't be happy either.
Our favorite narrator-mouse decides it will be best to check in with his Grandmamma to ask her advice. He and Bruno plan to run like crazy through the hotel in order to get to her.
