Everyone going to Venus has to go in order to meet the rocket’s weight limit. But the group splits in three and do it in that many different ways: Ric and the Mayor get a relaxing spa and shiatsu from Jacqueline; P-Ko, Stella and Nino go on a strawberry-only diet, and Sister puts the brothers, Last Samurai, and Hoshi through hellish boot camp that awakens their muscles.
The muscles theme takes over the weight-loss theme (which is fitting, as muscles weigh more than fat), as everyone but Tetsuro loses all their bulk quickly after not working out. He continues, however, leading to hubris and arrogance that gets him into a battle with Stella, who is no slouch even before she transforms into Mega-Stella. Everything about this absurd battle and its faux-drama was hilarious, and the fight animation wasn’t bad, either.
