Tap and hold these animated realistic 3D tyrannosaurus rexes and play music. You can strike a chord of up to five t. rexes.

They move their tails, open their toothy mouths and emit loud scary prehistoric roars. Each dinosaur corresponds to a piano key with realistic pitch intervals.

Thus, you can play as if you were playing the piano. But t. rexes are much cooler and scarier. You should hear it!
