Kesesese~! (Prussia aka Gilbert Beilschmidt’s ghostly disembodied voice can be heard all over the place wether it be a house, mansion, temple, church, theme park or anywhere else that is haunted as he is a ghost or in the German language a poltergeist) yep Prussia is a ghost aka a poltergeist and what he does is make loud noises, move objects and throw them at anyone and other things so it’s best to either survive or have ghost hunting equipment.
