Maybe I can try and de-code this.
Elsa and Anna may be stand alone characters along with Mickey,
Crystal Sully, Mr Incredible, Lightning Mcqueen, Lone Ranger, Buzz Lightyear and Jack Sparrow are some kind of clear variants, similar to "Blue Bash" from Skylanders.
"Worlds of Ralph" may seem like a triple pack, because of its price, compared the below playset (which is 5 bucks more), and because WIR isnt going to have a playset. Hopefully this would include Ralph, Felix and Vanellope.
Girls Pack is another 3 pack that would include girls, Probably Jessie, Elsa and Anna.
Hope this helps
