Glitter 'N Grow Kitties & Puppies
The Glitter 'N Grow set consisted of adult kitties and puppies whose hair would "grow" if pulled from either the tail or the large plastic bow(s) on the head. When the hair from the tail was pulled it would get longer and the hair from the bows would shorten and vise versa. They could be purchased individually or in a 2-pack with a bonus pet that was a re-release of a kitty from the 1st original set.
