No, gmelon, it's the (extremely easy and straightforward!) Jean Greenhowe pattern in her Christmas Special book. The donkey, which I still have to make, is in her Christmas Treasures book.
I haven't seen a Noah's Ark pattern - that sounds interesting. Are the Alan Dart patterns simple? The JG ones are all very simple and the instructions are meticulously detailed. I saw on her website that she's always designed them all so that anyone who just knit and purl, increase and decrease, can easily tackle them.
