To be honest, the third one felt a bit like a downgrade from the previous 2. Mainly due to the fact that you can't customize the duck's color.

I just really miss those hats and colors...
The oragami characters are from other games sponsered by Armor Games. The following are what you can get and the games they are from: Hedge Hog, Hedge Hog Launch; Turtle, Toss the Turtle; Penguin, Learn to Fly
tip: when you finish a battle save, then go to the market and click "Pandora's Box" and if you get nothing you can just load your game and you will still have your bonus points!
