Mother Dorrie

Mother Dorrie is an anomalous entity that can replace Dorrie in Hazy Maze Cave. It is a large black Dorrie-like creature with white a large white stripe that goes from below their head to the underwater portion of their body and large, spiky teeth. It will rush towards the player faster than they can run. When caught, they will be eaten and then be presented with the game over screen no matter how many lives they had.

Possible Defeat
Using a nearby Metal Cap, it is possible to damage Mother Dorrie, though nobody has done enough damage to defeat the monster. It is currently unknown what happens when Mother Dorrie is defeated.

Sign Connections
Near the lake where Mother Dorrie can be found, there is a sign that reads:

"Underground Lake

Right: Metal Cave

Left: Abandoned Mine

(Closed)

A gentle sea dragon lives here. Pound on his back to make him lower his head. Don't become his lunch."

Seeing as Dorrie never attacks the player, it is possible it refers to Mother Dorrie.
