This is a collaboration pajama set between Tabekko Doubutsu and Shakkure Planet! All the Tabekko Doubutsu animals have the Shakkure (protruding jaw) look! The pajamas have an all-over pattern. The fabric is as thin as a long-sleeved T-shirt, so it's perfect for this time of year or in the spring. It looks super cute on kids! (^-^)
