Does anyone know if the new shape Leapster fits securely in the carry case or if it still moves around? DD has the old shape Leapster and carry case. DS has the new shape Leapster and we've tried it out in DD's carry case and there's too much room for it and it annoying slips about. I wondered if maybe the 'new' case has changed inside to create a snug fit even though it looks the same from the outside?
