I may be a rookie, but I'm experience in Pokemon....I got one of my pokeballs out of my pocket.
Come on out Sharpedo
I'd aimed the pokeball to the pool.
Sharpedo look around, he look disappointed.
It's just you and me today...I will teach you how to do Ice Beam.
Sharpedo shook his head left to right.
Oh come on....it's not that hard...it's really easy.

saw the new guy in the pool, he came to approach him

Training for ice beam huh?

I replied back.
um...yeah...I think Sharpedo is scared of the thought of ice...weird huh...

your sharpedo might not levled up enough to learn that move.train it to a higher level and it might learn ice beam.
