I do not own Gravity Falls.

Bill had been certain that making a human form for himself would be a brilliant plan. He had thought that appearing as an average person would be much stealthier than his usual triangular yellow self, however dapper he may usually be. He could directly interact with anyone, go anywhere nearly undetected, and practically do whatever he wanted.

He just hadn't realized that, upon changing form, that he wouldn't exactly be able to change back.

On top of that, he hadn't realized that having a human body was so difficult. He was so used to floating everywhere, he honestly had no idea how to use legs. And how was he supposed to maintain the obnoxious fluff on his head known as hair?

However, the absolute worse part was something Bill had not foreseen at all. Something that honestly came as a complete shock. Something that he didn't even fully realize was there until he awkwardly stumbled towards the Mystery Shack after still recovering from his transformation that had taken place in the nearby woods, eventually falling at the very edge of the trees and into the clearing. As two familiar figures ran towards him with confused and slightly concerned faces, his vision blurring and his body feeling faint, he was eventually hoisted up by the two, and a few strands of long, curly brown hair fell onto his face, and he could feel a soft sweater rubbing against the back of his hand.

It wasn't until he was being dragged towards the shack, barely conscious but feeling much warmer than the brisk evening should have allowed him to be, that it dawned on him that with a human body came pure, raw, and dangerous human emotions.

And that was the one thing Bill was not at all prepared for.
