Mordecai and Rigby are a great team. They do almost everything together and they can even find ways to make their job fun. But sadly sickness is also a thing. One day Mordecai gets so sick, that he can't turn up for work. Rigby has to do their job alone and also check how his friend is feeling every once in a while. He thinks that this will be easy as pie, but he finds out, that the work doesn't roll so smoothly without his buddy. It turns out that Mordecai actually does a lot of things, that Rigby struggles with. That's how the raccoon learns the importance of team work and the joy of having a best friend around.
