Your idea for a device that cleans the ocean floor is both creative and important. I love how you’ve designed it to move like a dolphin - using a propeller is such a smart way to help it glide through the water! The camera to find rubbish is a fantastic addition, making sure nothing gets missed. I also think it’s really clever how it can fool animals so they stay safe while the rubbish is collected. You’ve thought of so many great details, Isabella. Well done!
