For all of my decorations, I used Cake Mate writing icing kit. The icing is for writing so if you're thinking about more cupcake designs, I suggest you get more than one box. The box comes in four colors: red, blue, green and yellow. You can get them at your local grocery store and it costs about $4-$5.
For the character eyes I used Betty Crocker black decorating gel. Sometimes icing from decorating tubes can be a bit challenging to create tiny dots, like eyes, on cupcakes. At least for me, I have a hard time cutting off tube icing when I have the desired teeny tiny amount. So using decorating gel and a toothpick, for tiny objects like eyes, usually helps me get the desired peepers on my characters.
Here's how they turned out:
