A round green thing

I got up from the blue rug. Walking feels clumsy, but my legs work. I climbed onto a small wooden side table next to the glass tank. There was a big green melon sitting on a plate. It smelled sweet. I wanted to show it to the goldfish, so I tried to push it closer to the glass. It rolled fast and bumped right into a ceramic mug. Oops. The syringe on my head wobbled, but it stayed on. The fish swam over and looked at the melon. I think we are friends now.
