And yet another folktale inspited fakemon, this one about the rolling head of the captain Jean Soulard who leaves a trail of blood wherever it goes, of course I couldn't put something this gruesome in my dex so I improvised with a boulder ~

#043 Loleye | Ghost/Rock Type

The rolling head Pokemon

Loleye use it's internal core, often mistaken an eye and teeth, in order to move as this vengeful spirit cannot exit it's vessel. If provoked, it is said that Loleye will stalk their prey, rolling wherever it goes until they meet their demise after which they will devour their soul. Signs of their presence can be seen by the trail of ectoplasm they leave behind them.
