Dress your child up as the cute and lovable Boo, from Disney/Pixar’s Monsters Inc. Boo, a name given by the blue monster Sulley (aka Kitty), is a human child that stepped into the Monster world. In the animated film Monsters Inc, she wears a half monster, half alien type costume to hide her true human self. To dress your child up as Boo, you’d need a whole body suit that’s purple and scaly. You’d also need a pair of antler-type eyes, and shoe-lace type hair. Get your child to say “Kitty” and she’ll be all set! For the next best thing, you can opt to simply carry around this adorable Boo plush doll instead, at the very least to satisfy your kid’s demands if you don’t want to fashion a Boo costume up for her.
