Otto the Octopus loves doing everything a young octopus loves to do like skateboarding, riding his sea horse, searching for pirate treasure, ice skating (upside down) and swinging from the sea monkey bars. However, he has 7 misadventures and breaks his legs, so he has to see the Doctorpus and the Sting-Radiologist who help him get better. When his casts come off, physical therapy makes him stronger than before so he can get back to playing tangleball and helping his mom cook minnow-stroni soup.
