Henry finds Schwoz up-ended and stuffed into a container of animal feed labeled Holland Oats, which references the musical duo Hall & Oates.
Schwoz's sister Winnie is played by Kevin Allen - a rare occurrence of a female character played by a man in a Nickelodeon show.
Henry's "Feels gooood" has been added back into the opening title sequence.
At the time of production (May 2016), actor Jace Norman, who plays Henry Hart, had turned sixteen two months prior. That would make him age appropriate for being a high school sophomore, yet Henry Hart is in middle school (now, as of this episode, called a junior high school).
The episode title "The Trouble with Frittles" is a reference to the Star Trek episode "The Trouble with Tribbles".
