It was lively day at the Octopod, everyone was doing the jobs, when Captain Barnacles said:

Captain Barnacles: Good work everyone! Finish off what you have, it's almost lunch time! Remember I'm here if you always need and extra paw!

He said, then going back to his room. The Octopod was like home away from home for everyone, hence why we all had our own offices and rooms.
