Green Original Kids Morphsuit Costume - size Medium 3'7-4'0 (108cm-122cm)

On the blue suits what color is the morph suit written in??

What size should I buy for a child that is average size 9years old

How small is The writing on the red suite and what color?

Im not fully understanding the "fast release velcro hood." Is it removeable, or does it open to expose the face? A pic would be appreciated.
