Popo

ポポ

A highly agile boy belonging to a race known as the "forest people." He is friends with all the insects in the forest. His clothing consists of grass, and his weapons are handmade boomerangs.
He embarks on a journey with a circus troupe to search for his father and investigate the cause of an unusual change in the peaceful forest.
He possesses the Protector's Proof, a mysterious acorn-shaped pendant left to him by his father. The Protector's Proof emits a light that summons the "Mushiking," a mysterious and powerful beetle, to aid Popo.
