Ep. 74: Captain Ginyu... The Frog
Realizing that he's no match for the renewed Vegeta, Captain Ginyu decides to use his body-switching trick on him. Once again, he lets his body get thrashed, so his opponent will be very weak after the switch. Just as Captain Ginyu uses the trick, Goku recognizes the move and intercepts the light beam, switching back into his old body. Back in his broken body, Captain Ginyu tries to switch with Vegeta again. Goku throws a frog to intercept the transfer. The frog, in Ginyu's body, hops into the water, while Ginyu, in the frog's body, flees. With the Ginyu Force defeated, Goku recovers in an isolation chamber in Frieza's spaceship. Vegeta finds two pairs of Saiyan armor for Krillin and Gohan to wear in their upcoming fight with Frieza. (Source: Wikipedia)
