Jammyfish[1], originally known as jellyfish[2], are jellyfish-like enemies found underwater in the Bigmouth Galaxy and the Deep Dark Galaxy in Super Mario Galaxy, and in the Cosmic Cove Galaxy in Super Mario Galaxy 2. In Super Mario Galaxy they can be found swimming around in groups of four, or moving around alone, and hurt Mario if he touches them. In Super Mario Galaxy 2 however, they always appear alone, and move back and forth or in a circle. They can be defeated with either a spin or a Koopa Shell and give a coin when defeated.
