A cannibalistic fish who eats anything and everything (even other fish) to have a big home all to herself.

Eeek!
There were several fish in the fish tank living with Gillyweed. Then all of a sudden there was one less fish. And then another disappeared. And finally, the last fish living with Gillyweed was found severed in two; head and tail were found floating at the top of the tank. And Gillyweed just got bigger and bigger.

Don't be a Gillyweed! Cannibalism is BAD!!!!
