Weedle

Often found in forests, eating leaves, Weedle have sharp, venomous stingers on their heads. In "Challenge of the Samurai," Dexter the Pokedex recalls encountering this shy bug Pokemon meeting up with Ash and Pikachu. As Ash traveled through the forest searching for new Pokemon, he encountered a timid Weedle. The Weedle, in a flurry of fright, climbed high up into the trees to escape.
