A + C + B wins.

"What the heck? Why is this 'Bidoof' staring at me?"
The Bidoof continues to stare.
"Why do you even exist? What is the point of your life?"
Bidoof the Buck-toothed stares at you, even more stupidly than its previous owner did.
You decide to try to make it do something.
"GO, POKEBALL!"
The spoiled milk explodes all over Bidoof's oily fur. Suddenly, the Bidoof leaps in the air, does a barrel roll, tries a somersault, and begins gnawing chunks out of its fur. You kick the Bidoof right in the belly. It squeals like a boiling piglet.
"I could get used to torturing Bidoofs," you think to yourself happily. The smell of the chocolate milk, however, is getting to you, so you recall Bidoof the Buck-toothed to its Pokeball.
"Now, lets see about that journal."
You open the front cover. Crayon scribbles cover the inside. You roll your eyes and flip the page.
"DEER DIARY 2DAY I GOT ON GAMESPOT I YELLED @ SUM NOOBS BCUZ THEY THOUGHT SHADOW DA HEGEHOG WAZ A BAD GAME THEN I GOT ON UTUBE AND WATCHD A VID OF SUM GUY DANCING HE SAID SUMN ABOUT RICKROLL'D IT WS 2 FUNNY LOL BYE DIARY I LUV U SO MUCH"
Disgusting. He not only talked like a noob, he wrote like one too. Good thing he's just a puddle of flesh, unable 2- I mean to- pollute the internet with his trash again.
You're a little bored, what should you do now?
[A] Bidoof-beating festival!
[B] Read more of the diary, I guess.
[C] Finally try to save Dawn?
