Plot
Trivia
Trolley Troubles is one of Epic Mickey's transition levels, set as one of the 3 trials Mickey must go through before meeting Oswald himself. A major difference in the level is that, while the cow refused to move and Oswald ended up squeezing underneath her in the cartoon, Mickey can hit a switch that spooks the cow into running off, allowing the trolley to continue.
