I was there in late May, noticed it was gone, and asked the CM at the F&G merchandise stand that was there instead where the beads were. He said they were gone. I said "gone for now or gone forever?" and he said gone gone, as far as he knew, but that I was not the first person to have asked about it.
I tweeted the WDWToday account about them and they said "Unfortunately, they are no longer available. We apologize!"
I followed that up by asking if they'd be back at some point and got "You never know what will be featured at our merchandise locations!" as an answer.
I meant to email at some point about it. Perhaps I will do that now.
