Giant mini alien

So, you all saw that adorable mini alien I made for a mystery knit? (I won't bother linking to it, because it's the entry just below this one). Well I decided it was so cute I wanted to make another one, and because I'm just plain weird I decided to do it with the biggest yarn I have. Which turned out to be Sirdar Bigga, a 15mm yarn. For the uninitiated, a normal double knit yarn is about 4mm.
