Steve & Blue teach the viewers on simple machines that make things move or work.
This article needs a recap. Watch the episode.
The skidoo tone for going home (often used when skidooing into the place) from Snack Time was heard again for the fourth time on this episode.
When Steve goes from the skidoo location to the Thinking Chair, he pretends to drive a car, even when he skidoos out.
He even honks the Blue Skidoo theme before skidooing.
This is the last time (until Signs) where Steve stands up in a stripe backgrounds holding up his notebook for a couple seconds and tells the viewers he needs their help to figure out the answer to Blue's Clues.
This is the fifth episode where two clues are found and drawn outside with only one clue found inside.
