Imagine a giant, scaly log that got angry one day and decided to grow legs but forgot to take a swimming class. It has a mouth full of oversized teeth, like nature's version of a bad dental plan, and small beady eyes that seem to be judging your life choices. It lounges around in muddy water, pretending to be a boulder, then suddenly turns into a surprisingly quick, thrashing creature when it’s time for lunch. It's basically a prehistoric reptile that thinks it's a water ninja but looks more like a dinosaur that lost a fight with a swamp.
