Cooking a thin snail is required for the task called "It's Only Wafer Thin", to complete the Easy Morytania tasks. Thin snails are also used at level 13 Summoning to make thorny snail pouches. Players may receive thin snail from opening a box of summoning ingredients, a possible reward from the Familiarisation Distraction and Diversion. There is a right-click option to 'Grind' the thin snail. This is used to produce Blamish snail slime used in the Blamish oil for the quest, Heroes' Quest. You are required to have a sample bottle in your inventory to collect it.
