Bongsan

Bongsan (Geunduun) was a "Cloud" in shape of a dog and was one of the three treasures of Sun Wukong. He accompanied G-Big as he guarded the entrance to Middle Town. After G-Big's defeat, Bongsan was handed the "Key of the Release" to the gate for safekeeping, which he buried.

Similar to goblins, Bongsan is able to use magical skills (e.g. Goblin Mask).

After the buried key was found by Pajuju (allowing the reapers to enter Middle Town), Bongsan enlisted Gwangnam's help to get the reapers back.

G-Big saved Bongsan from eternal destruction by Bobbobbob, allowing Bongsan to go to Gwangnam's aid in fighting Jordy and Pajuju. Bongsan then allowed Gwangnam to ride him in order for Gwangnam to beat Pajuju and retrieve the Key of the Release.
