Green Bunny is the name of my favorite stuffed animal as a young child. He's a green bunny.
I've had him since birth, and he was my best friend when I was really little.
When I was 8, my dog Lady was apparently jealous of him and my sister's favorite stuffed animal. She took them both out out our bed while we were sleeping, brought them to another room, and tore Green Bunny up. She hadn't gotten to Valentine Bear when she was discovered by my father. That morning sucked.
His face was mostly destroyed and he lost stuffing. Keep in mind he's not very big. Never found his eye or nose. He went into a box which I said was a "hospital bed" because he was in a "coma". I vowed to fix him. My sister insisted the box was a coffin.
He stayed there for the next 12 years, until I realized that with my weaving abilities I now had the skills to fix him. So after a long quest for similar materials (yarn, nose, and eye), I was able to make him whole again. (And so he finally came out of his "coma".
I guess the whole thing is a little goofy, but when I was 8, I made a promise to him, and while he isn't technically real (as in alive), I wasn't going to break it.
So, my username is in honor of him.
