For those not familiar with a mirror hey for three [per Jonathan S], but familiar with the
square dance "Dip & Dive" figure, the W/Lizard Walk piece can be taught as a
"Dip and Dive past two" then same thing but in reverse. Then all that, but
without hands, and upright! 
"Here's what your feet will do, we'll teach it with hands first, then
without,  but make sure your feet learn this:
Keep your partner's hand facing this way - up or down - the whole time. 
2s arch, 1s dive,  all forward to the next.
1s arch, 2s dive, all forward then stop. Now back up:
2s arch, 1s back under/2s back over, 
1s arch, 2s back under.
"Let go of your partner, let your feet do the same thing but without arches and
dipping and diving:
1s split the 2s, all forward.
2s split the next, 1s on the outside..
Back up, 1s inside split the 2s, 
then 2s inside split the next 1s."
Or something like that. Credit to Carol Ormand.

That's your feet pattern: do the same thing without your partner's hand.
