Pomegranate
Fruit of Prosperity
According to Professor Juniper, nobody knows where Klink came from. They suddenly appeared in Chargestone Cave over one hundred years ago.
The mystery surrounding them fascinates me. I am hoping there is an anime episode to tie in with that part of the game, except with Juniper giving a much more in-depth explanation.
See that's the kind of thing that makes inanimate Pokemon so much more interesting than the ones based on animals! I mean it's easy to just say "Pidgey was always there because they're like birds and birds have always been here", but there's no easy way to explain them away so they give rise to a lot of fun theories.
