It's sounds like a slow, shnazzy version of the Pac-Man music that plays during intermission. It also makes me think it could be the theme for the "cool" side character of an RPG.

The player's party is trying to make its way to Mole Vale, but, suddenly, Bertn comes tumbling out in front of them wearing rainbow suspenders and round purple sunglasses. 4 Wood begins to play as the team tries to figure out who this amazing stranger is that impedes their journey. After an enthusiastic introduction, Bertn demands they prove themselves worthy of proceeding through his enchanted forest by competing against him and his colorful band of hat-wearing squirrels in a goofy song & dance battle that's essentially a rhythm mini game.
