While you're visiting the stegosaurus exhibit, you notice a screen. You touch it, and it glimmers to life. "This is the stegosaurus! These things weigh more than an elephant, but can also outrun most predators! Fun fact: did you know that a stegosaurus has a brain the size of a walnut?" The screen suddenly displays a warning. "Please do not do anything to antagonize a stegosaurus. Though they are herbivores, they posses spiked tails and will use them against potential threats."
