Matilda, your invention, the Crab Clawer 11,000, is incredibly imaginative! It's clear you've put a lot of thought into creating a fun and eco-friendly sea ride. The idea of using seagrass to power the ride shows your awareness of renewable energy, and the clever use of technology to classify rubbish highlights your commitment to a cleaner ocean. The luxurious features, like the couch-bed and TV with 11,000 channels, sound both entertaining and innovative. Keep dreaming and inventing, Matilda—your ideas could inspire a whole new way of experiencing the sea!
