Defeat These Terrifying Enemies! Krillin's Fighting Spirit Returns!Android 18 arrives at Master Roshi's house and searches for Krillin. Master Roshi and Fortuneteller Baba explain that Krillin and Goku have entered the "Forest of Terror," which is a place where they have to face illusions of enemies that they had battled before. Master Roshi intended this exercise as a way to help Krillin overcome his lack of confidence. In the forest, Krillin is terrified by what he sees. Among the group of illusions are Tambourine, Frieza, Dabura, and Majin Buu, where all of them previously killed or seriously wounded Krillin. Overcome with fear, Krillin attempts to abandon the race and fly out of the forest. The trees move to block the entrance, which leave Goku and Krillin stranded. The illusions attack and separate Goku and Krillin. Krillin finds himself surrounded by the illusions, but his attacks only make them stronger. After slicing one in half, he discovers that they are powered by his own energy. He heeds Master Roshi's training and calms himself down, which weakens the illusions. As a final challenge, Fortuneteller Baba summons an illusion of Super Shenron, which immediately ensnares Goku. Krillin quickly arrives and frees him. The two of them use a combined Kamehameha blast to destroy the illusion. The illusions turn into the rare herbs that Master Roshi wanted. Goku and Krillin return to Master Roshi's house with bags full of the herb. Master Roshi admits that there is actually no secret technique. Krillin, who has regained his confidence, disagrees. Goku and Krillin soon leave. Krillin returns home, where Android 18 shaves his head. This signals Krillin's decision to pick up his martial arts training once again.
