- Daniel Chong explained that this episode was created by doodling Grizzly gags, pulled out the funniest jokes, and stitched them into an episode plot. He describes this episode as a weird one.
- In "Burrito", Ice Bear reacted strongly to the rotten scent of the burrito, however, at the end of this episode, he completely ignored Grizzly's incredible odor as if he wasn't stinky at all.
- The ad for someone to go back in time is most likely a reference to an infamous ad that actually did appear in a magazine called Backwoods Home Magazine.
- When the episode starts, the rise and fall of Grizzly's back is out of sync with his snoring.
