Pile of items
A pile of items.
Literally a pile of items. Each pile can hold only 100 items, not counting any that are in containers, though the containers themselves are counted as items. Putting dirt into a pile of items and then removing the other items forms a pile of dirt, which does not raise the tiles below it, allowing for easy storage. 4 items must be on a tile to spawn a pile of items, which appears as a topless wooden box with tools inside it. The pile appears differently if items of a single type are in the pile.
