[1] Muskrat Lake is home to another paranormal phenomenon: local legends state that an Atomic Energy of Canada bus driver saw an extraterrestrial spacecraft landing on a spot atop a hill and leaving.

Mussie's diet, according to self-proclaimed observer Donnie Humphries, consists at least partially of cattails found near the edge of the lake.

In local folklore, it has variously been portrayed as akin to a walrus;[3] a sturgeon or other fish; or a Loch Ness Monster with three eyes and sharper teeth.

The creature's name was originally cited as Hapyxelor, alternately spelled Hapaxelor, but changed simply to Mussie,[2] short for The Monster of Muskrat Lake,[1] sometime later.

[2] Scientists have also surveyed the area and found nothing, though the definitive nonexistence of a Mussie-like creature is difficult to establish because some of the trenches in Muskrat Lake extend to over 60 metres.

[1] Mussie has become a cultural mascot of the area, appearing on signs welcoming visitors to Cobden and in front of the Home Hardware store in the village.
