Captain N: The Game Master

The episode "How's Bayou" has two different versions. The original version aired on September 16, 1989 and never again. It had a lot of unfinished/raw animation, different music/dialogue/scenes/etc., and a lot of other little differences. The "finished" version aired all subsequent times. Strangely, the Shout Factory DVD includes the rare, first version, and not the later better-known version.

King Hippo is blue-skinned on the show, but has a normal flesh color in the game Punch Out.

Three of the episodes were trimmed down to half of their original length and aired as filler material in Super Mario World (1991)
