Hello Kitty no Fushigi na Mizuumi

Synopsis

In Hello Kitty no Fushigi na Mizuumi, Kitty and Mimmy go fishing with their Papa and hear about strange occurrences at a nearby lake. Later that evening, they encounter a creature resembling the Loch Ness monster along with a fairy. The monster complains about its unhappy existence in the contaminated lake, where illegal dumping has driven away most of the fish. To help, the girls seek out a wise grandmother witch to give the monster the ability to fly so it can move elsewhere. But the monster asks the witch to also remove the trash from the lake. After the lake is cleaned, the monster can once again live contentedly in its home.
