(heh, heh, heh) I know what the birdy was! Twas Articuno! Yay, Legendaries! (sorry, sugar-high) I'd like to see more of these one-shots.

Not bad! I really like the way you switched tenses at the end, and your trainer's self-deprecation appealed to me. I'll keep looking for more stuff!

Oh. I like! Short and sweet.

Well, I like it.

But it feels underdeveloped, as Farla said. Very underdeveloped.

Maybe you should have made it a little longer. Numb doesn't mean you can't move. Or you should have started with this guy on his knees, feeling very weak. Should have said that he had been trying to get away for a couple of days now.

There should have been more of a build up before Arty came in as well. Perhaps put the reader in a bit of doubt about what was going to happen.

Research before you write.

Eh. This feels underdeveloped and your description/research could use some work. Have you ever been numb? There's a big difference between having your fingers without feeling and clumsy and being unable to move your entire hand at all. If his hand wasn't able to move, he'd have lost it, no question. One also doesn't go directly from fine to shivering to near death.
