Joltik

Joltik appeared in 2010 video game called Pokémon Black & White. Joltik is an Attaching Pokémon. Joltik can't produce their own electricity, so instead they attach to larger Pokémon and suck up the static electricity that are given off. They store this energy in a special pouch.

At 4 inches (0.1 meters) tall, Joltik is one of the smallest Pokémon in existence. It has four legs tipped with blue, conical feet. Its ovoid body is completely covered in yellow fur, with notable tufts sticking out on each side of its face, just over each eye, and its lower back. Joltik has four blue eyes. The two larger eyes are set relatively far apart on its face, containing black pupils. The two smaller simple eyes are situated between the first pair, slightly higher up on its face. Joltik's mandibles point downward and reside at the bottom of its face, where they closely resemble tufts of hair.

Joltik is too small to generate its own electricity, so it attaches itself to larger Pokémon and feeds off their static electricity. It will also make its way into houses and feed off electricity in electrical sockets. All of the energy it absorbs it stores in an electric pouch on its body. As seen in the anime, Joltik is not especially aggressive, but will defend itself if bothered. It has been demonstrated that if Joltik is unable to find a source of energy, it will be unable to move and in serious danger. Joltik, and its evolution Galvantula, are the only Pokémon that can learn Electroweb by leveling up.
