I wore this costume to homecoming week at my school where the theme was each of the Disney parks (the main ones).
Tree of Life! There are 16 animals total hand drawn onto the dress. The 5 on the bottom front are the 5 animals in the logo, which (fun fact) represents the 3 types of animals: living, extinct, and nonexistent. The three living are obvious, the extinct is the dinosaur, and the nonexistent is the dragon, which is part of the original park design for a section called "Beastly Kingdom". It had a good side and a bad side that battled each other and featured other mythical animals. It was scrapped due to budget cuts but there are still a few aspects such as the Unicorn parking lot, the dragon head above the ticket booth, and the dragon in the logo. Expedition Everest is the only ride for mythical creatures in the park. The other 11 animals include: Eagle, bear, owl, peacock, snake, whale, ant, beetle, bat, tortoise, snake, and monkey. Each animal represents some kind of animal type (nocturnal, reptilian, mammal, bird, etc).
