This small spiky-backed dinosaur is a vibrant sight to behold. It scurries along the ground, dragging its long tail behind it. Its head is small and its eyes are beady and bright. Its small mouth is filled with sharp teeth. Its body is covered in scaly, greenish-brown skin. To color this fun dinosaur, use bright, lively shades of green to bring out its scaly texture. You can also color its back spikes in cool blues and purples, to make them stand out against the rest of its body. Don't forget to add yellow to its beady eyes, and a dark shade of brown to its sharp teeth. Finally, give it a gold or orange tail to complete the look.
