From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Planet Bihe (ビーへ 惑星, Biie Wakusei; FUNimation "Planet Beehay") is a remote planetoid-asteroid in the North Galaxy.
Planet Bihe appeared in "Lord Luud". It was infested with Muma. The Parapara Brothers led Son Goku, Trunks Brief, Son Pan, and Gill into its maze of tunnels after they stole one of their Black Star Dragon Balls. Earlier, when the Parapara Brothers consulted their spaceship'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 Muma. After the travelers from Planet Earth became lost in Planet Bihe's tunnels, the Parapara Brothers withdrew from the asteroid and returned to Planet Lood.
As the Parapara Brothers had planned, the Muma soon attacked the Earthlings' spaceship, but Goku, Trunks, and Pan were able to fend off their attack. The Parapara Brothers soon returned to Beehay when they learned that their victims possessed yet another Black Star Dragon Ball, and attempted to steal it using their signature dance. The return of the Muma startled the Parapara Brothers, however, and Goku, Trunks, and Pan were able to retake control of the situation. Soon thereafter, Pan and Gill inadvertently left Beehay when they accidentally activated the autopilot on the Parapara Brothers' Spaceship. Goku and Trunks followed and brought the Parapara Brothers along with them as captives.
