I watched a movie called 'Wall-E.' It's about a small robot named Wall-E who cleans up trash on Earth. Earth is empty because it's too dirty for people. Wall-E is lonely until he meets another robot named EVE. Together, they go on a space adventure. The movie shows how Wall-E cares for Earth and finds love. I like this movie because it has funny and sad moments, and it teaches us to care for our planet.
