The Sun is a prop character that appears in the background of center stage behind Dook LaRue in The Rock-afire Explosion. Like the Moon, it would often sing backup. In personality, the Sun had a mellow, peace keeper type of attitude.
It should be noted, however, that the Concept Unification Prototype Stage, the Sun was removed entirely in order for a traveling Mr. Munch animatronic. It should also be noted that a different version of the Sun was used on Pasqually's stage. This version of the Sun had sunglasses and was most likely a decoration .
