Monty is the secondary antagonist in Trumpet of the Swan.
Monty is conman in Boston. When Louie came to Boston, Monty heard his music and thought it would be a perfect oppertunity for him to gain lots of money, so became a manager and agent to Louie. But when Louie was going home to save Sarena from marrying Boyd, Monty tried to stop him (like cutting his wing feathers), but with the help of two squirrels, Monty stuck in a lampshade and Louie got away. It is unknown if either Monty got arrested, went to go find Louie, go back doing card games, or doing a different approach.
