Old School RuneScape uses the British convention for floor numbering: Ground floor, first floor, etc.
A Premade t'd crunch is a type of gnomish food that can be bought from the gnome waiter in the north-west corner of the first floor of the Grand Tree. Premade foods cannot be used in the Gnome restaurant minigame.
Premade t'd crunches can only be used to heal 7 hitpoints, just like the Cheese+tom batta food that can be made by players with the Cooking skill.
