Extend the Story - Add a Room

You grab a Pokeball and stare at it. Guilt overcomes you and you leap up, throwing the Pokeball with all your might. It smacks the Machoke in the head, causing it to turn it's attention on you and growling.
Thankfully an orange Pokemon had appeared. It stared at the Machoke, wide eyed.
Noticing the fire burning on the Pokemon's tail you shout out, "Ember!"
Instantly a plume of brilliant orange red flame shot forth, scorching the Machoke which gave a shout of alarm. the attack wasn't strong enough to damage it enough but it turned it's attention on you.
"Tackle!"
The Charmanded lowered it's head, dashing at the Machoke and ramming it in the neck at full speed.
"Ember!" you shout, getting into the battle now.
Machoke gave a cry as the flames hit it. It rocked for a moment before falling back, fainting.
"Thank you, you know. You're not bad," Professor Oak says as he rises to his feet. Behind him Renji fixes you with an unreadable stare.
"That was a superb way you fought. Would you like to be one of my helpers in filling in the Pokedex?"
You nod rapidly. After all, your dream was to travel around meeting Pokemon.
"It seems you have no Pokemon. Would you like to keep Charmander of take one of my other Pokemon?"

I think I'll stay with Charmander
