Sorry - Disney Version
With the Disney version there are four cards that have an extra ability. The 3, 5, 8, and the 12. They only take effect if the card played is the same color as the players pieces. Only the Blue player can use the Blue cards and so forth. So basically, the blue cards only have "special powers" for the blue player and the same for other players.
The deck has only one card of each number for each color.
If the card played is the players color they can move one of their pieces forward that number of spaces or:
#3 Look at the top three cards in the draw pile. Choose which one to play. Place all three on the discard pile when done.
#5 You can move one piece from each opponent BACK five spaces. This does not include those in Home or in the Safety Zone.
#8 Move two pieces forward eight spaces. Do not move one of your pieces forward sixteen spaces.
#12 Move the lead piece directly to you Home. This is the one closest to your Home even if it is already in the Safety Zone.
Note: These cards are no longer made and buying them can be expensive depending on when and/or where you search for them. It's suggested you make your own. Just write the four colors on the cards. Each color gets one of each of the cards.
Variant:
Deal five cards to everyone. On a players turn they choose which card to play. After the play, draw another card.

Here's an example of the blue cards. The cards for the other colors/players are basically the same except for the characters.
Take a look at the board and pieces. Pretty neat.
