While I was drawing Larry, I thought about having his tentacles holding stuff, like his Starbuck's cup and cell phone, but then I remembered I already did that shtick earlier, and decided to skip it.
Drawing Tip: If you want an object to look moist and slimy, all you have to do is draw a solid white highlight on the side facing the light source. Works every time.
Drawn in Photoshop on the graphic tablet.
Here's the original sketch of Larry. Mostly the same, except for the final drawing I evened out the size of his hands.
