Leaving leftover black tea unattended is asking for this Pokémon to come along and pour itself into it, turning the tea into a new Polteageist.
Polteageist is a Ghost-type Pokémon. It takes double damage from Ghost and Dark, resists Poison and Bug, and is immune to Normal and Fighting. Its base stats add up to 508: the highest is Special Attack (134) and the lowest is HP (60).
It is the second stage of its evolution line, along with Sinistea. Its ability is Weak Armor, and its Hidden Ability is Cursed Body. It is in the Mineral and Amorphous egg groups and, being genderless, can only breed with Ditto. In Scarlet and Violet it learns 15 moves by level-up and 37 by TM.
