Oliver seems to be shy at first but he eventually opens up when he starts talking. Oliver has a puppet called Mr Buttons, made out of a sock and loose buttons, but when lost him during his and Brianna's 'play date' he was very upset about it. Although Brianna didn't like Oliver at first they are now considered friends and possible crushes. He even made her a crumpled up, yet cute valentine. In The Misadventures Of Max Crumbly, Oliver scribbled his ABCs all over Max's Air Jordan sneakers with a permanent black marker.
Oliver has bangs and light-colored hair. His hairstyle is similar to Marcus's. He has a nice smile and wears Mr. Buttons everywhere, like Brianna do with ms.Penelope

His grandmother is Mrs. Wallabanger, Nikki's neighbor.
He has lost Mr. Buttons at one time, which is how Maxine was made.
