Dragon Ball - episode 5 - 25 Mar, 1986

Bulma forces Oolong to join their group, thinking that his shape shifting ability will come in handy. Their boat runs out of gas, so they have to walk through the desert. Yamcha, a dangerous bandit, is said to live in this desert. While they walk through the desert, Yamcha and his shape shifting cat Puar ambush them. Goku and Yamcha begin to fight. Yamcha thinks he has won after he uses his Wolf Fang Fist, but Goku is able to get up. Just as Yamcha is about to attack again, he sees Bulma. Yamcha gets nervous around girls, so he panics and runs away. (Source: Wikipedia)
