Um... You seem to be forgetting recent history here. This is not the first battle in the tunnels. a turn or two ago Sizemore crushes the first scouts in the tunnels, mainly marbits. During this time Wanda was otherwise disposed so it would explain why these bodies were not uncroaked.
Tss, tss, forgetting? Uncroaked bodies go away at the beginning of the next turn, and GK and Jetstone had turns after that. (ninja'd)
By the way, when I read the strip I thought of those two as different golems (the liquid one lacks the spikes on the shoulders).
