Things You May Not Know About Pukei-Pukei


 * Pukei-Pukei is a poisonous Bird Wyvern that feeds on certain types of nuts and all sorts of plants.
 * When it eats, it is known to store some of the properties of its food in its mouth and tail before combining it with its poison. This allows for Pukei-Pukei to spew poison from its mouth and tail.
 * Due to this strange ability it is sometimes called the Poison Calamity Bird (Japanese 毒妖鳥).
