Looks like people want me to expand this topic so others can get in on the fun.
Feel free to do your own "A Day in the Life" with another character.
A Day in the Life of Appa
9:00 am: Woken up again by tiny girl who likes to start earth quakes. She's really starting to piss me off.
9:30 am: Eat breakfast of hay provided by goofy bald boy. Man, this kid is needy. Stop hugging me already.
11:00 am: Flying monkey thing talks my ear off again. Would like to bite monkey's head off, but bald kid is always around. ...Maybe later.
12 noon: Bald kid, tiny girl, naggy chick and loud guy hop on my back and expect me to fly them places -again. "Yip yip"? I got your yip yip right here, you lousy...
2:00 pm: Stop for lunch. Surprise -more hay. Where's the meat? I should just eat you all. Especially naggy chick. Mmm, dark meat.
3:00 pm: Bald kid engages in another round of "snuggle the bison." Sheesh, kid, get a girlfriend already.
4-8 pm: More flying around. You people would be so screwed without me.
8:00 pm: Finally stop. Break camp for the night. Tiny girl and naggy chick go at it. Whoo-hoo, Cat Fight! Kick her ass, naggy chick!
11:00 pm: For some reason we're flying again. Whatever.
1-5 am: Stop again. Start again. Stop again. Start again. I think we're being chased.
7:00 am: Flying yet again. Decide to play prank -pretend to fall asleep. Kids yell in terror as we plummet towards ground. Bwahahaha! Psyche!
7:10 am: Tiny chick and naggy girl go at it again. Darn, no blows thrown. Appa wanna see some mud-wrestling! Tiny chick storms off. Good riddance.
8-9 am: Given bath. About time, people! I still got Swampbender stench all over me! Wait, am I losing all my hair? Great, just what I need, to look more like bald boy.
10:30 am: And we're flying again. Bald kid goes off alone. Forgets to hug me. Thank God.
11:30 am: Crash land. Sick of this BLEEP. Going to sleep. A depressing-looking chick and her busty friend attack us. Yeah, right. Have fun swimming, beeyawches!
12-3 pm: Left alone with yapping monkey thing. Too tired. Kill later.
4-7 pm: Kids are back. More flying. Surprise, surprise.
9:00 pm: Break camp. Sleep -finally!
9:15 pm: Bald kid makes lip-smacking sounds in his sleep, mutters "Katara, I wuv you." God, what a loser. Somebody kidnap me, please.
