So it has been shown that the Water Bois have sorta hidden abilities... Like how they can blow up floaties super fast, or Moon can turn his mouth into some sort of lighter and light candles. How they can break their own rules and stand on slides and surf down them, looking cool while doing it...
Do they have any other abilities or talents??
Yeah, just restating what you’ve already found they have lungs for blowing up floatation devices and for CPR emergencies. (Also giving them the ability to whistle)
Moon has a mechanism in his mouth to dispense fuel and spark it for fire performances at the luau. (Also to light candles as we’ve seen, hehe)
The boys can retain and dispense water at will, allowing them to be fully submerged and control how much they float or sink, if they need to swim, or if they need to work while being grounded underwater. (It’s also why they have the ability to cry) ^^^ On top of this they can retain water to make themselves heavier on land (like a lot heavier) for construction, security, anything that needs heavy machinery.
They know they are not human, and that their bodies can take much more than what ours can, hence being hypocrites with their own rules. :) At least (for the most part) they do a good job demonstrating rule following behavior when guests are around. They just pushed it when y/n came along, as we have seen (Slide was closed off already so no witnesses for their more intense antics haha)
