Beehay was first seen in "Lord Luud" when the Para brothers led Goku, Trunks, Pan and Giru into its maze of tunnels after stealing one of their Black Star Dragon Balls. Earlier, when the brothers consulted their ship's computer with regards to a plan to evade their pursuers, it suggested that they lead them into the asteroid to be eaten by the Mouma. After the travelers from Earth became lost in Beehay's tunnels, the Para brothers withdrew from the asteroid and returned to Planet Luud. From Dragon Ball Wiki, a Wikia wiki.
