I'm too lazy to put the images, too much coding, so...

---

Bow: "Hello"
--- if bowing back and forth, "Hello you deer" (i see multiple deer in close proximity to one another)
--- if spinning in a circle, "Goodbye."

Bow + Sad: "Hello...*sad*"
--- if spinning in a circle, "Goodbye...*sad*"

Head tilt + Sad: "Huh? That's strange...*looking at ground*"

Amazement: I see it more as..."RAWR!!!", not 'gasp' or anything.

ROTFL: "Hehehe!"

Anger (head down, antlers out): "Grrrrr....stay away..." (normally at an inanimate object)
--- if in the cage...I'm trying but failing to escape. I try and do this to demonstrate my inability to play right.
--- if after failing to sit atop a tree, I'm angry that I failed.

ROTFL + anything other than sadness: I'm trying to either hide or go through something...or I'm just bored.

Any action + fear: I may be trying to tell a story...or something.
--- if I'm changing masks, mooing, and I do that...the sound scares me.

Scratch the Ground: Look at the ground below me...is there something there? Like a rock? I might like it or want to show it to you.
--- if there's nothing below me, and I scratch twice, back up, then scratch once more...I see 21 right in front of me! (hehe)
--- if I scratch, turn, scratch, turn...I might be showing you how many deer I see in an area.

Stand on Hind Legs: Look at what's in front of me...it must offend me. If it's a tree or rock or something...I might have been swarmed by birds, and I'm freaking out.
--- if in the cage, I'm trying to get out...
--- if after failing to sit atop a tree, I'm angry that I failed.

Taunt: "Grr! I don't like you!" Probably to an inanimate object. Never did this to a deer before.
--- if after failing to sit atop a tree, I'm angry that I failed.

Sad + No or just No: I probably just casted a spell, and, as I guessed, failed.
--- if I spin around before/after...I know there are deer around me, but I can't see them.

Yes: If I'm standing inside the cage...it means, "Yeah, I'm trapped...ugh."

Sad + Lie Down: I'm sad, so I'm sitting down.

Scratch the Ground + Lie Down: I will be right back!

Roar: If at an object...I'm offended.
--- if I'm on the playground rocks or in the oak, I may want company.

Listen: I only get a few pictograms to spread out, so I listen to see where the deer whose pictos I loaded, are. I do this alot

Sniff: "You seem familiar..."

Nuzzle: "I recognize your pictogram, you're my friend ^^;"

Nuzzle + Hop: "I'm excited! I was lonely!"
--- if I turn around and hop and nuzzle and such...it must mean that the deer I see is a deer that I know is following me (by looking at the live map), and I'm trying to say, "I see you right here!!!!"

Cough: "See?...I can't see any of you. Otherwise, I wouldn't be able to cough..."

Hop (not running): "Whee...I'm bored."
--- if around something...I must like it.

If I'm spazzing out: I'm either bored, or dancing to a good song.

Walking slowly + occasional sad emote: Depressed and shy.

Occasionally sad emoting: Depressed and lonely...

---

If you see me...that might help you decipher what in the foofles I'm doing :3

Oh, and if you see me, but I don't get up from sleep...it's because I can't see any pictograms. You'll have to tell me that you see me...though I wouldn't do much.
