Choose The Form
Once in a while, folks might be approached with the expectation that they will make very difficult decisions. Now, sometimes, you're being asked this question by a dangerous gateway guardian that is expecting to destroy the world. (Thankfully, that kind of situation is pretty rare and you're unlikely to be asked for real.) Very often, you're asked what folks are going to have for dinner. That one is probably far more common (and strangely more lethal).
One that falls somewhere in the middle (and is far safer) is the question of what to do with your tyke and their Halloween costume. Clearly, their goal is probably centered around finding the best sweets out there. So long as you're not suggesting candy corn, you'll probably come out a-okay. But, if you convince them to go with the Stay Puft Marshmallow Man, not only do you get to appease Gozer the Destroyer, but you get to bring your kiddo into your favorite fandom!
Design & Details
It's time for the most adorable Marshmallow Kid that you've ever seen to stampede through the world and bring in a reign of fun. This officially licensed Stay Puft costume from Ghostbusters is a shirt and pant combo with a giant Stay Puft headpiece. The shirt fastens with hook and loops in the back and features the blue and white bib you've come to love. The pants have an elastic waist and along the legs to create stuffed segments. Finish off with the headpiece and your tyke is ready for a truly sweet time.
How About 'Delicious Fun!?'
When Gozer demands you to make some choices, we recommend highlighting the fun of the season with this Stay Puft Marshmallow costume, developed in our own in-house studios. Team up with some other Ghostbusters looks and you've got yourself the best movie apocalypse theme ever!
