I just watched it, so I thought I'd sum it up for you with semi-witty dialogue. =) Note, some parts were skipped because they were. Deal with it.
MAJOR BACKSTORY, LIKE EIGHT YEARS OR -SOMETHING-
Kari's Voice: Kay, I'm Kari, and my brother is Tai, and we kick ass because we're the main characters, 'cept I'm mainly the main character because I'm the narrator and I kind of sound like a little boy. Anyway, Tai has an overactive bladder.
Tai: -falls off ladder-
Kari: -stares at computer screen-
Tai: -gets out of bathroom-
Kari: -stares at computer screen & notices a damn lot of actions-
Tai: Wtf Kari go to bed.
Kari: The computer looks weird!
Computer: -pops out an egg!-
Tai: .. Wtf.
Kari's Voice: NEXT MORNING =) Tai talks about retarded things but I'm not really interested 'cause I'm just not.
Egg: -CRACK.-
Kari: Aww, little black thing. :3
Black thingy: -sux the face-
Tai: EW.
Kari: -follows little black thing playing an OBNOXIOUS WHISTLE, together they play the themesong with bubbles-
Black thingy: -DIGIVOLVE >> KURAMON (I think? xD)-
Kuramon: I'm Kuramon, Jackie thinks.
Kari: I'LL STEAL MY PSYCHO CAT'S FOOD
Cat: -pissed off- OWNED.
Kari's Voice: This isn't Tai's Kuramon we'll see in the future, so in all honesty I don't know why the fuck he's here. YES BACKSTORY. :)~
Kuramon: -EVOLVED INTO LIKE, MEGAHUGE AGUMON-
Agumon: PWNED. Which is better than owned. -gives Kari a piggyback ride, breaks soda machine-
Crazy-ass bird: -APPEARS FROM SKY!!-
