"Krabby live on beaches, burrowed inside holes dug into the sand. On sandy beaches with little in the way of food, these Pokémon can be seen squabbling with each other over territory."
Another perfect example of the Pokemon world imitating the real one, Krabby is...well...a crab. A powerful one, and with really big eyes, but a crab none the less. Krabby will actually forever have the honor of being Ash's 7th Pokemon, and even helping Ash win his first Pokemon League battle.
Krabby's Basic Attacks are Mud Shot and Bubble, while its Special Attacks are Water Pulse, Bubble Beam, and Vice Grip.
