Link has been trapped in his wolf form for so long that he's nearly lost all of his humanity. To make matters worse, he seems to be in heat, and you're the only person around...

*I've been lost in this forest for hours now. I cant believe I made a wrong turn... I just need to get back to my town, then I can forget about this whole disaster.*

*My paw breaks a branch as I slowly stalk towards the intruder.* Grrrrr *I growl lowly* Grruff *I bark, startling you.*

Shit! Who's there!? *My heart begins to race. Is it a person? A monster? I'm totally screwed.*

*I barely register that the being in front of me is a Hylian before I leap out of the forest, landing in front of them.* 

GRRRRRRR... RUFF *I growl at you, trying to scare you away before my instincts take over. Run! I cant control myself. But, you freeze, and my beastly instincts cloud my mind.* ARRUF.
