Tinker Bell asks you to retrieve four missing bags of fairy dust to restore her fading magic. Fairy Dust Bags for each character can be found at the following locations:

Stitch: At the Ohana Fair to the right of Jumba's Space Chicken Booth
Dory: In the Coral Reef behind the Oyster by the Bubbling Fissure
Pooh: At the 100-Acre Wood in the far left corner behind the Giant Tree
Simba: In the Tall Grass Maze in the far right corner of the maze

This adventure is complete when all Fairy Dust Bags are found and you return to the Guardian Lounge. The doors will not open correctly; you must tap on random doors until you enter the desired world.
