Ha! That's hilarious. I once tried to dress up my chihuahua, but she just trembled and quietly whimpered the entire time - wouldn't move for anything. When I took the costume off of her, she waited until I wasn't looking then chewed it up and peed on it. Glad Conan was a good sport because he looks smashing.
I searched high and low for the same thing and finally gave up. I'm in the process of trial-and-erroring my way through a dress pattern right now. I sort of cheated and used an existing dress I had to figure out the rough size/shape of the pieces, but I am new to sewing so that makes it pretty difficult. Sorry I can't help you, but hopefully someone else can. There's obviously a demand here.
I am pretty much THE biggest fan of all things He-Man so I actually sort of let some weird yip when I saw the thumbnail and scared the crap out of my cat. TrapJaw was my favorite ever so I'm in love with your plush version. Awesome job.
Mathematical! I am really loving this and am sort of surprised since I thought I was alone in my adult Adventure Time fanaticism. I'm actually working on a little stuffed Ricardio, myself. Anyway, very awesome job. I'm in love.
