He sports a signature mythical golden horn and a fun-to-comb mane and tail. Buttercup's durable plastic eyes are both charming and scratch-resistant. Hypo-allergenic. Ages 3 and up."

And the latest reveal is Trixie the Triceratops. The official toy description for Trixie? It's right here: "Trixie is a perfect playmate for prehistoric playtime! Visit the era when dinosaurs ruled the Earth! Made of rigid, durable plastic and in friendly shades of blue and purple, Trixie features an expressive mouth and movable legs.
