Graphic 90. Bit 0 of +14 says whether it has a quest item to go to. Until it has, it falls one unit a turn, and looks for a quest item not yet done (graphics 112 to 115) among the room's records each turn; the well's rooms have none, so it falls to the ground there and waits to be carried (TAKE_OR_LEAVE). Put down where a quest item is, it finds it, takes its U and V as the target, and from then on rises one unit a turn to a height of 176 while it steers towards the item (HEAD_FOR_TARGET), without falling.

When it can move no more -- above the item at the top of its rise, or stopped by something in every direction -- it finds the quest item in the room again and sets bit 0 of its +16, which QUEST_ITEM acts on. Then the bucket's work is done: BUCKET_OUT is cleared so the well can give another, the quest-item tune plays, the bucket's quest record is emptied, and the bucket turns into a puff (START_PUFF).
