I hit the witch task also though my witch was a little unconventional but totally applicable.

...There is a bright light and with some concentration I find myself standing in the living room. I look around for a witch but only see my black cat lying under the dinning table. Realizing animals are DCs too, I decide that this is the witch in disguise. I dive head first toward her and end up gliding on my stomach a long way. When I get to my cat she is now on the mat in front of the kitchen sink. She is lying there like some cat goddess and somehow looking very regal and highly intelligent. I say, "Witch. Hey, witch. Cast a spell on me... please." I put left hand out to her. She replies by putting a paw on top of it. As soon as she touches me, I begin to convulse uncontrollably and my skin turns a multitude of colors and patterns. First it's black and gray stripes, then yellow and orange stripes with yellow polka dots on the orange, then yellow and red stripes, a paisley pattern and so on. I laugh out loud and let out a goofy sounding "wow". The colors and patterns become more and more complex and I become lost in it like I am on some sort of psychedelic high. I hear a sound like a vacuum cleaner in the next room. After a moment every thing around me fades away and I am consumed by the colors and patterns. I enjoy the show for a moment longer until I finally wake up.
