Ya know, all of our observations, guesses, and ideas all seem to eventually bring up water.
And if you think about it wouldn't that be a cool if there was an event for making some kind of submersible?
It would probably cost more to do though.
Also what, wait
I just thought of another. The first clue said something about noodles and if it is pool noodles then it could be another reference to water. If anyone thinks of another kind of water reference let me know.
(You might want to use both clues)
