Oliver is quirky and a very strange boy, known for his strange dance moves and obsession with strange outfits such as "boynks", skinny jeans, and a tandem jacket. He is not very bright. He sold fruit bars them to Mitch Bilsky, and got bullied, but he was completely oblivious to this. He also seems to hold a grudge against Bianca, as she almost canceled Oliver's plans with Henry for that weekend.
