It mimics those classical carnival dark rides which had its guest travel both indoor and outdoor. The ride opened in 1958 with a little bit of delay but turned out to be one the first jewels of early Fantasyland.
Around the end of the ride, the caterpillar-shaped cars glide in the open to give their riders a stunning view of the matterhorn’s side and Mad Tea Party from above. Then it’s back inside for the Un-birthday finale.
