Join the Nintendo Fun Club

During the between-round scenes against King Hippo, Doc Louis will occasionally say:

"Join the Nintendo Fun Club today! Mac."

The Nintendo Fun Club was a fan club run by Nintendo of America with a quarterly newsletter available from early 1987. It ran for seven issues before being revamped as Nintendo Power magazine.
