The New Orleans Pelicans big man hit up Disneyland on Sunday and decided he wanted a ride on one of the oldest coasters in the park.

The problem ... leg room.

You can see in the pics, Davis went full knees-to-chest to fit in the bobsled -- and apparently, it worked. We're told he had a blast at the park.

Fun Fact: There's a secret basketball court tucked away inside the mountain. No word on if AD got to hoop in between rides.
