Hater's prolonged "Uh" as he and Wander are showering was recorded in one take.
At the end of "The Breakfast", Hater breaks the fourth wall by glancing over at Wander's panel.
In "The Breakfast" when Wander and Hater are seen showering, Wander can be heard scatting the song "Wander Over Yonder End Title Theme".
After filling their glasses, Wander says "half full" while Hater says "half empty". This reflects that Wander is an optimist while Hater is a pessimist.
The entirety of "The Breakfast" is presented in splitscreen.
