I have never, in my life, seen a Disney-sanctioned interpretation of any of their characters, or their likenesses, displayed in any company-sanctioned manner. Considering Disney will sue people for damage of copyright if they sell a mouse who looks like Mickey, only wearing white shoes, yellow pants, and red gloves, I find it highly unprobable to completely unbelievable that there are any Disney-created pornographies out there, much less a campaign associated with these movies, directed at children.
It sounds like somebody is pulling a fast one on you, and instead of researching it, you pass it on.
