A friend of mine saw a crocheted Doop on another website, minus a pattern, and sent it to me with a request to make one for his desk at work. David said he liked Doop because he looks like a demented pickle. I think Doop looks like a stoned pickle.
I'm not going to link to the original website, because it seems a little messed up that I came up with my own pattern and then link to it. So, I'm leaving the original unlinked and will post my own pattern here.
