Which is more impressive, this frog or this one!? Dino and Tetori battle it out! What Tetori brought back was an Ichthyostega that might have been the cause of the disease! What kind of mushroom was it that was brought in to make them bitter !? And what about Tiktaalik !?

As Dino was playing, Tetris discovered the hunter Mosasaurus ! Apparently, it has a terrifying jaw that can even take down sharks! What's more, it's said to be the " that tree " of the world , and the scales from it are so exciting!
