Why do you need a Sonic Boom Greeting Card?
Whatever the reason may be, here comes one. At the release of the Boom game, Game Stop began selling this greeting card for 2.49 in their store. It has a nice CG of everyone in action: Sonic using the energy beam, Sticks with her boomerang, Tails throwing an orb, Knuckles with his...fingers? & Amy getting ready to swing her mallet.
