Arctic Leech Ivy

A ground cover plant found in the frigid lands of the north. It sustains itself by absorbing heat from it's surrounding area. If any person or animal is unfortunate enough to step on it, it's small prickles will dig into it's victim and start absorbing the heat from their body. The ivy will not stop absorbing heat until the victim has a lower core temperature than the ivy. In which case it will detach and await it's next victim.
A Arctic Leech Ivy can usually be spotted by the layers of frost surrounding it as it had already sapped the heat from the ground it grows in.
As the Ivy grows, it's long tendrils will reach out searching for new victims. When a tendril has grown too long and cannot be sustained with heat from the main body of the plant it will detach and become the main body of a new Ivy.
