Luckily only one group of slimes was able to form a<a class="link link--external" href="http://i.imgur.com/Z5zv94R.png" rel="nofollow ugc noopener" target="_blank">pink greater slime</a>.  The others were in too little numbers to form another so they avoided the girls. The Greater slimes' long arms reached for the girls to attack (1d10=5) only for it to miss (1d10=5) leaving an opening for them attack.
