Variant of Jammyfish

Jellyfish[1] are enemies from Super Mario Galaxy. They appear in the Deep Dark Galaxy and the Bigmouth Galaxy. They are a large, blue variant of Jammyfish. If Mario comes in contact with one, he is shocked. They can only be defeated by hitting them two times with a Koopa Shell, and give one coin when defeated. After they are attacked once, they glow green, but do not act any more aggressively.
