|Within the underwater rapids is a formidable fish called the Eelongo. It races around so powerfully that it crushes anything in its path. That includes metal blocks. So follow the Eelongo to see if it breaks into any places you can't.|
— Daroach, in Kirby Mass Attack
Eelongo is an enemy and stage hazard from Kirby Mass Attack. Its only purpose is to swim straight forward, destroying anything in its path, including Metal Blocks. It appears in Dedede Resort - Stage 5, where its arrival will be forewarned by a school of small orange fish. Eelongo cannot be defeated, and will KO any Kirby it rams into.
