Mr. Ambrose is the librarian/cheerleading coach at Wagstaff School. He is shown to have a penchant for drama.
He has an important role in Gene It On where he is shown to be the coach of the Wagstaff Whalers cheerleading team. Because he'd failed to get the role of drama adviser which instead went to Ms. LaBonz, he decides to inject drama into the cheerleading squad. This leads to him orchestrating the drama that takes place between Gene, Todd and the team such as telling Todd to "get dirty" leading to Todd hiring Zeke to incapacitate Gene and leaking their routine to Melvin Laird Middle School at the regional cheerleading finals.
