Ep 3. Wish Upon a Coin

Mickey Mouse season 3 episode 3 is titled "Wish Upon a Coin". In this episode, Mickey and his friends are walking through a park when they come across a wishing well. Mickey decides to make a wish, but as he's tossing in his coin, the well suddenly swallows him whole.

Inside the well, Mickey finds himself in a strange, alternate world where everything is upside down and backwards. He meets a new friend, a magical genie who tells him that the only way to escape the well is to find a four-leaf clover. Mickey sets out on a journey through the bizarre world of the well, encountering all sorts of strange creatures along the way.

Meanwhile, outside of the well, Mickey's friends are getting worried about him. They must come up with a plan to rescue him before it's too late. Goofy, Donald, and Minnie all band together to try and figure out how to get inside the well. It's not easy - the well seems to be sealed shut - but they eventually come up with a plan involving a bucket and some rope.

As Mickey continues on his journey, he encounters one obstacle after another. He has to cross a rickety bridge over a boiling hot river of lava, navigate a maze filled with deadly traps, and outrun a giant, fire-breathing dragon. Along the way, he meets other trapped travelers who are all looking for a way out.

Meanwhile, Mickey's friends are making their way down into the well. They too encounter dangerous obstacles and challenges, but they persevere. They finally make it to the bottom of the well, where they find Mickey and the genie. The four-leaf clover is in sight, but it's being guarded by a massive, terrifying monster.

Mickey and his friends work together to defeat the monster and retrieve the four-leaf clover. As soon as they have it in their possession, the world of the well begins to change. It slowly transforms back into the park they were in before. Mickey and his friends are returned safely to the real world.

As they're walking away from the well, they hear the sound of a child making a wish. Mickey and his friends all look back at the well with fondness, knowing that they all have their own wishes that have come true. The episode ends with the gang heading off to enjoy the rest of their day in the park.
