"Last Stop on Serpent Road! Are you Kaiō-sama?" (終点～ん蛇の道！おめえ界王様か？, Shūtennn Hebi no Michi! Omē Kaiō-sama ka?; FUNimation "The End of Snake Way"; Literally meaning "Last Stop on Serpent Road! Are you the World King God?") is the eighteenth episode of the Dragon Ball Z anime.
After a rough day of training with Piccolo, Gohan rests for the next day. Gohan has a bad dream involving Raditz beating his father, and he suddenly wakes up. Gohan looks up at the moon which has mysteriously reappeared, and overcome by his nightmares of Gokū's death, he loses control of himself and attacks Piccolo (who arrived to see what's going on). Piccolo does his best to stop him, but once Gohan grew his tail back, sees the moon and transformed into a Giant Monkey, he was powerless to stop him. Piccolo tries to destroy the moon, but finds that it is a projection from Gokū's old spaceship. Piccolo destroys the ship, reversing the transformation. Meanwhile, after a long trip, Gokū finally makes it to Kaiō's planet, and finds a friendly little monkey, whom he believes to be Kaiō.
