When you visit Once Upon a Toy and/or World of Disney Store at the Downtown Disney Marketplace at Walt Disney World Resort, for $5.00, Disney will donate a Duffy the Disney Bear to Toys for Tots. Disney is joining in the spirit of giving and will also donate $200,000 to Toys for Tots this holiday season.
