Nogu's way of communication

Gyu Gyu is determined, persistent without getting too emotional, and easy going.
Climbs everywhere; it gets dangerous often.
He needs only a few seconds to clim up on the railings of the porch, which is about 1.70m tall, and of course, that is driving the parents crazy.
He has fallen from chairs etc, but his positive personality never stops him from challenging again and following his curiosity and joy.
