Unknown Creature No.15

Born from my mind and brought into this world. Unknown Creature No.15 lives! This unknown creature is probably one the most dangerous of my creatures. It does not know the term or meaning of relent. Once this creature detects a meal within the vicinity, (it is guesstimated that it can sense a meal from some were between 35-50 Yards away,) it will chase you down until it is either dead or your dead. So if you happen to be the thing it detected, your doomed. 

This creature is also known to fight things bigger then it and that are a threat to it, (it has a 54% success rate when hunting things larger then it or that are a threat to it.)

Here's some hot tips if you encounter this unknown creature:
1.) DON'T ENCOUNTER THIS CREATURE - (If you can see it it's too late.)
2.) Running is pointless - (this creature moves quite fast.)
3.) Don't bother tripping it - (it'll just get back up as shown above, or push itself along the ground with it's mouth open heading straight towards you; it can move reasonably fast even when pushing itself along the ground.
4.) IF you a properly armed your best chance is to chop it's legs off - (keep in mind even if you do somehow succeed it will keep coming toward you til, again, either your dead or it dies.)
5.) Write a will - (Most recommended tactic.)
