Good old "Gappa." It appears that they used to grow turkeys large and aquatic on our planet (back when it was prehistoric). A word to the wise when you find a monster that is small enough to capture: look for tracks near the monster. If you find bigger footprints than the beast you have captured, let it go and get the heck out of Dodge fast.
