Mickey tries for a relaxing day at the beach and maybe a date with Minnie afterwards, but his day is ruined by the return of the obnoxious Mortimer Mouse, an old rival for Minnie's affection.
- Mickey Mouse (voiced by Wayne Allwine)
- Minnie Mouse (voiced by Russi Taylor)
- Mortimer Mouse (voiced by Maurice LaMarche)
- The title is a reference to the short Mickey's Rival. The plot of this cartoon mirrors that of the short involving Mortimer attempting to show up Mickey.
- When Mickey gets skyrocketed into space, none of the states' names are correct except for California.
