Beelemo

Beelemo - a small aggressive creature, a combination of a bee and a lemon.

Beelemos are semi-peaceful creatures of Elteria, commonly found on Wood Islands. Will cast a harmless poisoning debuff, which eventually will turn player into a beelemo for 15 seconds. In that form, the player has 500 hp and the ability to double jump. Transformation can be prevented by killing the creature before the initial timer runs out.
