In "Headhunters," Mikey R. is seen during the re-opening of the Wax Museum of Mystery. He, like everyone else, is disappointed when it turned out that there was no free pizza at the re-opening. He is also considered a suspect of Wax Stan's murder, until Dipper and Mabel find out that both of his arms are broken from an unknown incident, ruling him out.
Mikey sports a long brown mullet, has a very large pink nose, and small ears poking out beneath his hair. He isn't shown with shoes. He wears a brown shirt and small shorts. Due to unknown reasons, he broke both of his arms and wears casts on both of them.
