Welcome to
planDisney, Amanda, I am so happy you stopped by about Experiment 626, aka Stitch, and his Hawaiian partner, Lilo.
Everybody loves a good birthday party, especially Lilo and Stitch. If you are asking about Dorothy the Dinosaur from The Wiggles then I want you to know The Wiggles and their friends are not a part of the Disney family so it is unlikely that you would see Lilo and Stitch hanging out with Dorothy the Dinosaur at
Walt Disney World Resort. Maybe they will attend a birthday party together in the future. Interestingly, however, they did appear on separate shows on Disney Playhouse years ago. If you want to meet Lilo and Stitch then make a dining reservation at
'Ohana. They would love to see you during the meal.
If you are not asking about Dorothy the Dinosaur from The Wiggles, then
please write me back directly with more information so that I can help get you your enchanted answer.
Enjoy making many Magical Memories.
