A Yahaha is a small woodland creature that looks like a mandrake root. It is small enough to fit in the palm of a medium humanoid’s hand and bonds symbiotically with larger creatures to provide mutual protection.

When you use an action to toss one of these creatures into the air, the Yahaha orbits your head at a distance of 1d3 feet and confers a benefit to you. Thereafter, another creature must use an action to grasp or net the Yahaha to separate it from you, either by making a successful attack roll against AC 24 or a successful DC 24 Dexterity (Acrobatics) check. You can use an action to seize and stow the stone, ending its effect.

A Yahaha has AC 24, 10 hit points, and resistance to all damage. It is considered to be an object that is being worn while it orbits your head. It can take no other actions while it orbits your head and confers its benefit. While unattuned or not orbiting, it can fly 20 feet or take the hide action. It has 10 in all its stats and no proficiencies. It is a tiny Fey creature.

Symbiosis. You can cast Barkskin on yourself at will while the Yahaha orbits your head, but the Yahaha is considered to be the one concentrating on it.
