The Snaptrapper has a diet of fish and other dragons and gets it's prey by it's chocolate smell it releases from it's four heads. It has a lot of venom and it is very stealthy. The closest dragon to the Snaptrapper is the Hideous Zippleback that has two heads and the Snaptrapper has four. It has a strong jaw and is part of the Mystery class. It is slow. It only comes in the one colour that is green and red (Green for the whole body and red spots). It sheds it's scales and then grows them back. It is a very tall dragon. The weakness of the Snaptrapper is that it likes rain a lot. They keep their mouth open while hiding, so they look like flowers. If anyone comes close it will snap on them.
