Any use for Shuckle

Open bag and stare at him/her.
WORTH IT

Well, just like a more common Unown.

Has the highest defense stat in the game, try prestiging.

Paperweight?
OBTW, I walked through a park, 2+ mile walk, that was a Shuckle nest. Caught 39 of them, and got a perfect IV at 75 CP. Laughed til it hurt!

Sorry Jan.
In nintendo games Shuckle learns moves which allow him to swich his attack and defense stats so he could become very strong attacking mon. But that's only in nintendo games.
Wobbuffet suffers from the same problem btw.

Rename him Shuck Norris and there's nothing he can't do.

The use of one more Pokédex entry!
