Insomnia
The Pokémon is suffering from insomnia and cannot fall asleep.
Super Luck
The Pokémon is so lucky that the critical-hit ratios of its moves are boosted.
Feared and loathed by many, it is believed to bring misfortune to all those who see it at night.
If spotted, it will lure an unwary person into chasing it, then lose the pursuer on mountain trails.
Widely shunned as a bearer of ill fortune. Upon crossing paths with this creature, I’ve been told one must chant “Workrum, Workrum—bad luck, don’t come” as a protective incantation.
