^ That looks awesome!!
Though (as-is) they'd be a little too sci-fi / futuristic for what I'd envision for the lagoon show, this tech could be incorporated into the Marvel section of the show, for a superhero, if the show was to showcase each Island.
But here's another thought... Who says the show has be related to the Islands? It could be its own stand-alone attraction, unrelated to anything else. Then they could use something like this for something like a sea serpent monster. Create a costume that would cover the man and the tube, and it'd look pretty sick! Especially since they can go in and out of the water. So many possibilities!
Nice find! :thumbs:
