I was getting a little worried but I bought a new case from Toys R Us today, and got lucky enough to get the 15 discs I needed in 8 packs (used the base to check what was in them before opening any).
Here's what was in mine as far as counts (If I didn't list it there was 3 in the box, most of the discs there was 3 of).
Rapunzel's Healing - 4
Phillipe - 4
Parking Lot Tram - 1
Wall-E's Collection - 2 (Both were in the last 2 packs I scanned, was worried there wouldn't be one)
Danville Sky - 2
Fire Extinguisher - 2
Will be returning 16 packs tomorrow to Toys R us
