The 100% polyester Spiderman Burst Kids 3 Piece Pajamas Set comes mostly at night. Mostly. Then, after a few days...the Spiderman bursts out of your chest! It's ok, Sigourney Weaver will show up like 4 times and take care of business. Wait...am I on the right page? I mean surely these 100% polyester Spiderman Burst Kids 3 Piece Pajamas Sets cannot possibly be confused with certain alien movies. Surely. Though Spider Man does appear to be bursting from one's chest on this pajama shirt. He's also bursting several times over all over the legs! Wow. That's kind of scary now that I think about. Regardless, this Spiderman Burst Kids 3 Piece Pajamas Set is made for the little web head in training(it comes with a shirt and sleep pants!). Just keep them from the radioactive spiders and we should be alright.
