Below are (what should be) all associated QuestIDs, ItemIDs, Achievement etc. Details on feeding the slimes are here if needed: https://www.wowhead.com/achievement=13715/from-the-belly-of-the-jelly#comments:id=3126516

I created a blue and grey version of an icon that could be used to mark them, attached below (as png since they don't support blp). Please don't feel obligated to use them; I made them when I was under the delusion I could somehow write this plugin myself. Haha e_e

For me, a very basic "icon gone once slime is fed" functionality would be great.

Thank you :)
