The lake monster, named Minne, that resembles the Loch Ness Monster is a social media guru, the Huffington Post reported.
Cameron Gainer created Minne three years ago, and in the past year partnered with the Minneapolis Parks Foundation to boost park attendance, CBS Minnesota reported.
Minne's location is always a mystery, but she tweets and Facebooks clues for her followers to find her.
"There is nothing better than walking around the lake and for the first time spotting Minne," Mary DeLaittre of the Minneapolis Parks Foundation said. "And it's not just once, they keep coming back and coming back and weaving stories around Minne."
Minne will start lake-hopping again this May.
