5x8 - Dragon Ball Z: Dragon Box

Satan, thinking that Cell's attacks are nothing more than tricks, is raring to fight. But before he can, a helicopter descends out of the sky, and Satan's two apprentices, Piroshiki and Caroni, leap out of it! They announce that they will fight Cell before Satan does. Cell easily deals with the two of them. Satan at last challenges Cell to battle, but is swatted away with no trouble.
