Acting Commander Zee's Personal Log:

Without warning, the first Grog that I encounter dives into the slime and starts swimming toward me... I always scored low on these Initial Contact situations at the Academy...

I have never seen a Grog swim, and I have to admit that I'm impressed! Those big flat feet that make them kind of lumber around on dry land are perfect for propelling their wide body mass through the thick ooze! They also appear to have long webbed fingers that act as front flippers when they swim, but they almost always keep them clenched up in a fist.
