The Summer Vacation Special (also known as the Movie Overview Special) was aired on August 3, 1992, between episodes 150 and 151. The TV special takes place shortly after the events of the film Dragon Ball Z: Super Android 13!, which was released on July 11, 1992, and features Goku and Gohan in tuxedos, discussing all of the Dragon Ball/Dragon Ball Z movies as of that point in time. The 43 minute special ends with Goku changing back into his regular get-up, while Gohan struggles to wrestle his tuxedo free, before personally advertising Dragon Ball Z: Super Android 13!, which was playing in Japanese cinemas at the time.
