Starting out as just a normal Burt, he was enlarged to massive size by Kamek. He’s more concerned about his modesty than actually beating Yoshi. Firing eggs at Burt the Bashful will cause his pants to fall. Once they’re all the way off, Burt turns beet-red and runs away. Kind of feel bad for the guy...
