Logo: On a blue background, a yellow, green, and white arrow slide in, all layered behind each other. They a move a bit before spinning around the screen, revealing that their copies of the Wonder Kids logo, which is a upright male symbol (or a incomplete Granada logo) with "WONDER KIDS" in it, stacked and in a bubbly font. They then settle to the center, with the yellow copy on top before turning white with a yellow circle in the hole.

FX/SFX: The spinning logos, the color change.

Music/Sounds: None.

Availability: Scarce. Probably on hentai tapes and laserdiscs like the infamous Lolita Anime.
