CRYOGONAL
No I don't know why I like it either. But everyone else hates it and that makes him cheaper.
MPC PLUSH
Yeah so Cryogonal got a plush somehow. It's part of a line called My Pokemon Collection distributed in 2011/12. It includes all Unova pokemon. They are small but detailed keychains, and can be registered on japanese phones to show others what you have collected. They can be won from UFO catcher machines.
GLOW IN THE DARK MAGNET
This magnet is about the size of a nickel and glows in the dark.
2012 METAL CHARM
From the recent charm release including all pokemon. I have a second one.
CARD
I included this card because Cryogonal has like no merch right now. ):
