Grouper Productions

(July 20, 1986)
Logo: On a green background with clouds, superimposed in the closing credits of a movie, is Grouper in a odd-looking font. On the left of the P is production and on the right of the P is co., ltd.. On top of the Grouper text is a drawing of a fish. The logo is superimposed on a pipe.

Technique: None. It's superimposed.

Music/Sounds: A older pipe sound from Super Mario Bros. and Super Mario Bros. 3, followed by some wind sounds.

Availability: Was seen on the Japan-only OVA Super Mario Bros.: The Great Mission to Rescue Princess Peach, but it is ultra-rare because the VHS is very hard to find. But, it can be found on a few Japanese Internet stores.
