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.
Oliver has bangs and light-colored hair. He had a nice smile and wears Mr. Buttons everywhere. He reminds Nikki of Brandon.
He has a sock puppet.
Nikki made him a hand puppet named Maxine. Maxine now stays in Nikki's sock cabinet.
His brother is Max Crumbly from "Misadventures of Max Crumbly."
It is very possible that Oliver might have a crush on Brianna.
His grandmother is Mrs. Wallabanger, Nikki's neighbor.
He has lost Mr. Buttons at one time, which is how Maxine was made.
According to Nikki, Maxine is Mr. Button's long-lost sister.
