You guys say he is waterproof, which would be fine with me if it weren’t for the fact that we see water pouring out of him. You could say his internals are waterproof, but when we get glimpses of them there are exposed servos and circuits. It’s okay, ESB is still my favorite movie, but this In my mind is a flaw.
But since this isn’t happening in our world or our time, this criticism is useless.
We see the water pour out of him and he still works fine. Checks out to me.

“R2, stay and watch over the camp.”
(nervous beep)
Yep. The answer is in the movie!
