Xuanzang and his disciples encountered the leopard demon. The monkey tricked Pigsy into fighting off the demon. The demon returned to the cave and selected three capable goblins to change into his appearance to lure the monkey, Pigsy, and Sandyaway while he kidnapped Xuanzang. The disciples eventually recognized the scheme and found the cave. With a fake skull,the demon and his goblins claimed Xuanzang had been eaten, but the monkey saw through the ploy. The demon tried again with a real severed head, which sent the disciples into tears. When the monkey went to seek revenge on the demon, he discovered that Xuanzang was still alive, so he used sleep bugs to put the demons to sleep while he rescued Xuanzang. He then captured the demon, and Pigsy burned the cave.
