Hold on! Time to sit back and relax because you are looking at the coolest onesie we have available at the moment (I know… in matters of taste, there can be no disputes but it is our humble opinion). Having previously featured Mario, Luigi and Yoshi it was time to turn the trio into the legendary quartet by adding the one and only Bowser. The coolest onesie you have ever seen! From the front this onesie already looks impressively dangerous, but once you look at the back and see the dangerous pointy shield of this Bowser onesie, you want no other, right?
