Another idea by me :)
Bees, Beehives and Honey.
Bees: Bee's can only be spawned from beehives. It's a very tiny mob almost like a Silverfish.
The bee's can fly. They get angry if you punch them or if you punch their beehive.
A bee can be killed with only 2 punches by your hand.
If you are holding a flower of any kind bee's will not attack you, but they will follow you.
Bee's drop 0-2 honey when you kill them.
Beehives: Beehives spawns bees over time if you are near them. They always hang in trees.
If you destroy a beehive 5 bees will spawn and attack you, but the beehive will also drop 3-5 honey.
Honey: You can get honey by killing bees or breaking beehives.
Honey can be used to make Jars of Honey.
Jar of Honey: You can eat Jars of Honey. It will heal 4 hunger-points.
They can be crafted by placing 4 honeys as a cube.
