This is a submarine which is propelled by wind. You would launch it in and it would launch the propellors above water to move. Once it’s travelled to the coral reef, it will submerge and deploy its feet. It would then drill the bad bacteria out of the good coral.

What a magnificent idea you've got there, Ethan! 🌊 The Coral Cleaner 2.0 sounds like a truly inventive way to help protect our beautiful coral reefs. Using wind to power a submarine is super clever – it's like an eco-friendly superhero, flying through the water to save the day! Maybe its little feet could even do a fun coral reef dance when they touch the seabed. 😉 Keep dreaming big, Ethan!
