“It all started with the mouse!” Walt Disney Company employees say. Mickey Mouse is, without a doubt, the best-known cartoon character on the planet. He's also the corporate icon for one of the most powerful entertainment companies in the world, as well as the face behind the world's most popular theme parks.

In fact, you'll see this famous mouse everywhere you look. Throughout the park, countless “Hidden Mickeys” show up in the rides, attractions, landscaping, and other structures, an ongoing tribute to the rodent that started it all.

A Hidden Mickey is an image or outline of Mickey Mouse concealed in a Disney attraction's design. According to the unofficial Hidden Mickey website, these Hidden Mickeys started out as inside jokes among Walt Disney Imagineers. As you explore the Disneyland Resort, keep your eyes peeled for Hidden Mickeys; they're everywhere! The whole family can have fun looking for them. Who can spot the most Hidden Mickeys each day?
