What was that sound

Whoosh splash bang crash, What was that sound. Its sounds like crashing boats. But what could it be. Could it be the sound of the rainbows end bumper boat that dad wont let me go to even though I really want to. One day I want to go to this one because I am now tall enough to go on the best rides of all. And so being a height of 137 is the best because the best rides are in the 120 and 130 height position.
