The good thing about amigurumi crochet is you can more or less make what you want. For those of you who have Whovians in the family, Lucy Collin has put in a lot of work to create a really nice Dalek pattern which would also be suitable as a child's toy. Choose your colours and know it will stand about 7" or just under 18cm tall. If you are an experiences crocheter you would be able to adapt the pattern to a smaller version of this. If you are interested in the pattern you can find it on the -love- crochet site. If you are interested in how the pattern came about Lucy explains it on her LucyRavenscar blog.
