He glows softly at night in yellow, blue or pink providing comfort in the dark. As an added bonus, Night Owl also features Onaroo's "OK to Wake!" green light in the morning. Toddlers can take this cuddly friend beneath the covers or to the potty. The Night Owl lives in his included AC-powered tree branch base or runs on ordinary AA batteries when removed for take-along fun. When Night Owl is placed on his tree branch, batteries are not drained at all. This dual-power arrangement maximizes battery life while still providing a portable friend that toddlers can carry wherever they go.
