Jigglypuff can use an assortment of attacks including Pound and Rollout but it's signature attack is Sing that can put opponents to sleep. Although Jigglypuff isn't as well known in Pokémon Red and Blue compared to Pikachu, it's incusion into the Super Smash Bros. series most likely came from it's role in the anime.
