"You have to learn to rely on yourself. If you can find the courage to survive on your own, you'll be a stronger fighter both in body and in mind. Remember, there's a great power inside you waiting to be unlocked, but it's up to you to bring it out. Use it, rely on it, and if you can do that, I guarantee you'll live through this. "
Day 1 (恐竜とサバイバル! 悟飯のツライ修行, Kyoryu to Sabaibaru! Gohan no Tsurai Shugyo; lit. Survival with Dinosaurs! Gohan's Harsh Training) is the seventh episode of the Vegeta Saga and the entire Dragon Ball Z series. The episode first aired on June 14, 1989. Its original American air date was June 23, 2005.
Piccolo leaves Gohan in the middle of Break Wasteland, saying that he will be back in six months to teach him how to fight; if he cannot learn to survive on his own, he does not deserve to live, much less fight.
While Gohan bawls to himself on Earth, Goku tries to save some time by leaping entire sections of the very twisty road, but catches his foot on an incredibly sharp scale of the Snake Way and nearly falls into the depths of Hell below. Elsewhere, Krillin is picked to visit the homestead, where he has to break the bad news to Chi-Chi about what happened to Gohan and Goku, but when directly confronted with the Ox-King and his hot-tempered daughter, he can not bring himself to do so.
Gohan is chased by a T-Rex, and flees up a large rock formation, from which he can not climb down again. Piccolo secretly watches Gohan's activities throughout his time there.
- What happens to Gohan in this episode is similar to what Chi-Chi feared would happen to him in the previous episode: Chi-Chi predicted he would be left alone by Master Roshi in the ocean, swimming away from sharks to an island to fend for himself, she then thought he would want food and would climb a tree only to be bitten by a snake, causing his brain to be poisoned and to never be able to do math again. What truly happens is that Piccolo leaves Gohan alone and when Gohan climbs a large rock to get his coat, in which a snake was hiding but it did not bite him and instead left him alone.
- While visiting Chi-Chi and Ox-King at Grandpa Gohan's house, Krillin was dressed in a blue suit for the only time as an adult, which he also wore as a kid prior to and after the 21st and 22nd World Martial Arts Tournament.
