I have a 6 year old that also was extremly dissapointed. It took him a few days before he wanted to play it. This is a game made for kids and there is nothing to warn them up front that the character do not look like this in game. We wanted to see pumpkins on the ground when he did his "Up my brothers!"...
So my question to Activision now will be: Will the Jolly Bumble Blast and the Springtime Trigger Happy also be only painjob variations that will appear just the same as the other figures in game, or will those actually live up to the expectations of showing up as variants in game?
