What am I doing wrong?

[AprilBxoxo]

I have been trying to knit this horse finger puppet. After I get past the stockinette stitch for the first 12 rows, all goes wrong. I don't understand what I'm doing wrong. This is the part that gets me....the part that says form the nose. I keep getting holes from the slip stitches and it looks nothing like the picture at the end. Am I not slipping the stitch correctly or am I missing a step?
This is the webpage if it helps any.

Slipping a st is just moving it from one needle to another; it will be elongated, but shouldn't leave a hole.
