Wait, no, that's not what he's doing on the Spiderman Blue Button-Up Toddler Pajama Set...he is swinging, crawling and keeping those written sound effects company! Yeah! Coming as both a button-up collared t-shirt and matching pants, the Spiderman Blue Button-Up Toddler Pajama Set is a great set of PJs for that little web-head in your life.
