Homemade costumes of “Tweak” and “Kwazii Cat” the Octonauts. Would fit approximately a 5-6 year old (Kwazii), and 3-4 year old (Tweak”) The foam boots are just pieces that I tacked on to gum boots with hot glue (gum boots not included). I’m not sure if Octonauts are a thing anymore but my girls were thrilled with these costumes when I made them years ago. You can take one or both.
