Yes I see what you mean tuttle, not sure how to acheive that with the water, it's a terrain (to get the waves) over a water slab. Don't think there would be foam for gently lapping water, at least not from what I've seen and I've lived near water all my life, but something to be considered. Humorix, you're correct, the tentacles could have been done better. The ship is a small scout and must either get it's fuel from water (hydrogen) or skim a gas giant, so it landed in the water since it's easier. The alien is looking at something that interest him in the sky (they are explorers) what is not really important. What's important is that it distracts him from noticing the sea creature sneaking up on him and of course the guy refueling is ditracted from the danger as well.
