- "Carry more stuff."
The basket is a crafted item used to expand one primary inventory slot to hold four stacks of items rather than only one. It's strategically created by many players at the beginning of the game in order to allow a Blockhead to hold more ore, wood, fruit, etc.
 Where Found
A Blockhead will spawn with one basket.
If in a primary inventory slot, a basket can be expanded in three ways: by tapping the inventory hand, by tapping the basket slot itself, or by using a chest or other container. Upon tapping the hand or using a chest, all baskets in a primary slot will open; upon tapping an inventory slot, only that basket will open. Baskets may close after a delay, tapping a stored item, some drag-and-drop actions, or deselecting the in-use chest (but will remain open during any drag-and-drops or idle time while the chest is open).
Up to four stacks of items can be stored in each basket. A basket can be moved into another basket or a chest and all items within it will remain. However, the basket will not be usable until it is put into a primary slot.
Baskets cannot be stacked.
If no inventory slots are open and any primary slot doesn't contain a basket, a new basket will displace the contents of the highest primary slot that doesn't have a basket, take that slot, and deposit the slot's former contents into the right-most slot in the basket.
