What's your favorite Zoo exercises in Army Combatives?

One of my favorite parts of being an infantryman (4 years before reclassified to medic) was the crazy physical fitness regimes each leader brought to the table. My most favorite was when our combative level 4 squad leader would put the platoon through the "Zoo".
It's been over 5 years and I'm afraid I'm forgetting a few. I'll post what I remember, you guys add to it (with a brief description) or just talk about the ones you know and loved/hated. Sound good?
The Zoo:

Bear crawl
Caterpillar (on steroids of course)
Crab walk
