The story of the creature is prominent in southwest France. Part serpent, part snail, very big and long. Imagine a huge snail complete with slime and shell. They also have slimy yet hairy tentacles that can extend itself for more than a mile and they would eat humans.
They trap unsuspecting humans by hiding in underground caverns and leaving its slime covered tentacles extended on the ground hidden beneath a thin layer of dirt. Once you stand defenseless in the range of its tentacles, it would ensnare and paralyse you. Then drag you back to its lair where it proceeds on swallowing you whole with its gigantic gaping mouth.
