EUGY - a super-fun 3D puzzle that's eco-friendly and can be assembled in 10 to 20 minutes! This collectable toy is great for STEM concepts and craftable fun. Brontosaurus means "Thunder Lizard", a reference to the sound this giant dinosaur's feet must have made as they stomped the ground. While it was once considered to be a species of Apatosaurus, recent studies have shown that Brontosaurus is a valid dinosaur genus. While not as big as the real deal, this 3D puzzle is a perfect arts and craft activity to help pass some time and teach following instructions.
