Hiccup started pushing buttons now, right along with Ruffnut. One of them didn't do anything.

"This one doesn't even do anything. They have buttons that just exist to be pushed, that's ridiculous."

Then he hit the button that turned the water on. As the button he'd just previously pushed was not useless and was actually meant to make the water come out of the shower instead of the faucet, it meant that water suddenly shot down on him and Ruffnut. He sputtered in surprise and threw himself backward, landing on his butt the bathroom floor, his head and part of his torso soaked.

Then he started laughing and joke, "Guys, I think it's feeling insulted."

Clearly, the bath had feelings and it was attacking them now.
