So, right before the legs, you know how you've just closed up the body? DO NOT CUT THE YARN. Instead, slst directly into the bottom of the Squiddle until you get to the stitches you made in Round 11. At that point, ch5, slst 4; then, slst 3 directly into the bottom of the squiddle again. Three stitches should be what you need to space the legs evenly.

I hope that helps!
