"This Pokémon lives in cold water. It will leave the water to search for food when it gets cold outside."
Wooper are definitely one of those Pokemon where you aren't exactly sure what it is. It looks like a simple enough water creature, and yet it has antennae coming out of its ears. And by that we mean it looks like literal antennae. What makes it more interesting though is that this is the first ever Water/Ground type Pokemon, making it one with many uses.
Wooper's Basic Attacks are Water Gun and Mud Shot, while its Special Attacks are Body Slam, Mud Bomb, and Dig.
