Really because I bought 7 blind packs that all had 2 hexagonal discs in them and got this
1. Alice in Wonderland Terrain and Alice in Wonderland Sky
2. Finding Nemo Sky and Alice in Wonderland Sky
3. Rapunzel Sky and Finding Nemo Sky
4. Finding Nemo Terrain and Kahn
5. Alice in Wonderland Terrain and Finding Nemo Sky
6. Rapunzel Terrain and Sugar Rush Sky
7. Alice in Wonderland Sky and Stitch Blaster
I got Alice's Sky in 3/7, Alice's Terrain 2/7, Finding Nemo Sky 3/7. I got my first Marlin's Reef in a gold pack from Toys R Us, I think it was Tron Sky so obviously that one is harder to find. If you're getting 3 of the same disc in 7 packs that's a common disc, more common then others it seems. I only got 2/14 discs that weren't sky or terrain.
Edit 12/5: I took the other 7 back and got 7 new ones
1. Rapunzel's Terrain and Cinderella's Coach
2. CHROME Armor Shield and Rapunzel's Terrain
3. Stitch's Blaster and Kahn
4. Finding Nemo Terrain and Rapunzel's Sky
5. Alice in Wonderland Sky and Terrain
6. Rapunzel Terrain and CHROME Armor Shield
7. Rapunzel Terrain and Cinderella Coach
I got 1 repeat from last time and 2 sets of the same discs. But I did get 1 new disc, CHROME Armor Shield, still no Sugar Rush Terrain though.
Edit 12/7: I got 12 packs from Target this time and got 3 more I needed for Series 1, Abu the Elephant, King Candy's Dessert Toppings and Pieces of Eight. I still need Buzz's Space Ranger Spin.
