This episode of Dragon Ball is about Oolong trying to see Bulma's panties. Also there's some preliminary matches for the Tenka-ichi Budokai (which Goku, Kuririn, and Yamcha are participating in). As the preliminary matches are held in a private room, Bulma bullies Oolong into hoisting her onto his shoulders so she can look in through the building's high windows. So Oolong takes advantage of the situation and sneaks a peek at her panties. This works out until some creepy, smelly guy (more on him tomorrow) presses his face against the glass.
Bulma is frightened and topples over, taking a startled Puar with her. Puar latches himself tightly onto Bulma's face... and her legs are spread for all the gathered spectators to stare. Heroically, Oolong blocks her panties from view of the (other) peeping toms.... but takes advantage of the situation for his own benefit.
Meanwhile, there's the preliminary matches going on, featuring such contenders as;
Kuririn's bullies from Orin Temple.
Our heroes easily defeat each of them, and graduate to the true Tenka-ichi Budokai!!
