The first Piko Piko Hammer Amy wielded had a narrow red head, flexible yellow faces, and a purple handle. In some portrayals though, these colors have been inversed. In most cases, it has a red head with yellow faces. The Piko Piko Hammer commonly resembles a double-faced sledgehammer or mallet. She was given the hammer as a weapon in order to strengthen her tomboyish nature (note that this is also the reason why she is a playable character in the game). The Piko Piko Hammer made its first appearance in Sonic the Fighters, in which Amy used it as a part of her combat moves. The phrase "piko-piko" is an onomatopoeia for the chirping sound that these hammers make when struck (which can also be heard in several games when Amy attacks).



The Piko Piko Hammer was originally based on a popular Japanese children's toy of the same name.
