You can't blame the Angry Birds for being so mad when those Bad Piggies just refuse to give up their plot of stealing eggs. The Adult Angry Birds Yellow Bird Costume features an over-the-head plush yellow bodysuit with a print of Yellow Bird's sour face, complete with stern red eyebrows. The costume also features tufts of black fabric feather detail in the back and on top of the costume, and has helpful arm and face holes that allow you to have full visibility and maneuverability in the costume. To keep it look plush and hold its shape, you should stuff two or more pillows in the costume so that it keeps it. Wear this to a humorous theme costume party and get a ton of high fives from everyone present. Any Bad Piggies will make sure to avoid you at all costs.
