General Blue is gay in the original, which was why all of Bulma's advances didn't work on him.
Bulma's underwear is completely different than the pair she had on in "A Trap Is Sprung". She obviously couldn't change into neither a different pair of underwear or a swimsuit considering she didn't have anything with her.
Goku: (to Octopus) Ah, I know what you are! Eight legs...you must be a spider!
Bulma: (to General Blue) Hey there big boy, come to this underwater cave often?

Japanese Title: Alright! The Treasure Is Discovered
In the edited version when Bulma tried to stop General Blue from killing Krillin, a close up shot of her breasts and hips she was jiggling to distract him with was cut.
