Which Disney character is the star of the 1940 short Mr. Mouse Takes a Trip?

Mickey Mouse is the star of the 1940 Disney short Mr. Mouse Takes a Trip.

The cartoon follows Mickey as he attempts to travel by train with Pluto. The conductor refuses to allow the dog aboard, so Mickey devises a series of schemes to keep Pluto hidden. The setup creates a sustained sequence of visual gags involving luggage, train compartments, and the conductor.

Mr. Mouse Takes a Trip belongs to the period when Mickey’s cartoons increasingly paired him with established friends such as Pluto. Although Mickey remains the title character, Pluto’s presence is central to the plot and can make the short feel like a Pluto cartoon to modern viewers.

The title’s formal “Mr. Mouse” wording is also a reminder that Mickey’s name was sometimes presented differently in short-film titles. The cartoon is not the same as Pluto’s railway-themed solo adventures.
