Fruit
From The Blockheads Wiki
Any item that spawns on a tree in The Blockheads is either a fruit or a seed. All fruits are edible, while the same isn't true of seeds.
Where Found
The various fruits spawn on the leaves of associated trees (or cacti), where they remain until harvested, dropped due to the leaves despawning, or despawn themselves. Most fruits appear during specific seasons according to their type.
Uses
Any fruit may be eaten to restore part of a Blockhead's hunger bar.
Any fruit may be placed in a block of dirt (sand for prickly pears) or compost to spawn their parent plant.
Two fruits (the coffee cherry and the mango) can be used when crafting.
Most fruit can be used with time crystals to warp in additional blockheads into a world.
