There's a lot to take in when you're exploring Zootopia.

And with six animal-filled burrows—Bunnyburrow, Little Rodentia, Rainforest District, Sahara Square, Savanna Central and Tundratown—rookie police officer Judy Hopps (Ginnifer Goodwin) has a lot of ground to cover. Though the eagle-eyed bunny has a knack for spotting trouble, even she might miss the Hidden Mickeys in Walt Disney Animation Studios' buddy cop comedy.

Zootopia is currently the second highest-grossing film of 2016, with $984 million and counting. Ahead of its June 7 release on Blu-ray, Blu-ray 3D, DVD and Digital HD, directors Byron Howard and Rich Moore talked to E! News about how some of the Easter eggs were buried in the movie.

Five Hidden Mickeys are uncovered in the video above, but there are plenty more to be found. "I don't even know where they all are," Moore admitted. "I probably know the tip of the iceberg of the Hidden Mickeys."

Howard credited the "very sneaky" animators with giving fans a little something extra to discover. "Clawhauser is a good example. To our knowledge, he is the first Disney character to have a hidden Mickey on his person in one of his spots. That came from Cory Loftis, who designed him. So being cheeky and a sneaky guy like he is, he hid a Mickey onto his cheek."
