The Legend of the Fire Rhino

The Legend of the Fire Rhino is a legend known in the Kalosian culture.

Story
Legend say that a jungle on the center of Asia, close to the north of Kalos, caught fire one day. A rhinoceros was left behind and was burned alive. Later on, Mother Nature replanted half of the woods, only to have it being burned again. Thankfully, all the animals saved themselves. However, legends say that the ghost of the Fire Rhino, as a terrifying fire-burning rhinoceros, will come attack you if you leave fire unnattended. And to this day, you better be sure to put out the fire if you don't want the Fire Rhino to destroy you in your sleep.

How to prevent it
The only way to stop the Fire Rhino and save yourself, is to have a bucket of water or a Water-Type Pokémon beside you. Throw water over him until he was burned to ashes. Unfortunately, the very second you turn around, the Fire Rhino will turn back up again, and will come for people who leave fire on while distracted or asleep.
