Grumps is a witty character, His design resembles an animatronic mascot from the 80's. think of characters such as Grunkle Stan from Gravity Falls for his personality and voice. Most would consider him rude but it's part of his charm. His voice needs to be relatively deep, if you sound young this role might not be for you. Please have fun with the audition, try your best to show what you think you could bring to the character.
