Joe and Blue teach the viewers about who did what and how to make people feel good.
This episode is all about actions and consequences. we learn that by doing certain things, we can cause things to happen or make people feel a certain way. For example, Tickety makes Shovel mad when she knocks over his block tower and we find a way to help her out. After mail time, Joe nearly tripped over a stuffed zebra, but then he put it back. We skidoo to Blue's school, where we explore sharing and taking turns.
When dressing up in silly things at the end of the episode, Blue does a Groucho Marx impression.
In this episode Joe made Sidetable sad by asking her for the notebook without saying please. That part referenced Blue's Sad Day because in that episode Steve did the same thing Joe did.
This is the second appearance of Mouth and the first appearance of Curved Line and Giggles.
