Though in the intro Lumpy's right antler was pointing up and his left one was pointing down, but throughout the entire episode Lumpy's left antler was pointing up and the other one was pointing down, this is one of the rare episodes where Lumpy's antlers don't change direction much to his screen time.
This is the third time Flippy has asked a character to be quiet, before flipping out due to a disturbing noise created by the character (i.e. loud chewing). The first was Keepin' it Reel and second was in Random Acts of Silence.
The scenes with Flippy lifting himself up while reading a book on his hammock, Lumpy's garden flamingos moving above the fence, and Fliqpy running toward Lumpy with garden flamingos in his hands can be seen in the Still Alive Out NOW! video. The last mentioned clip is the video's thumbnail.
In the flashback, Flippy's fellow soldier is shown to have a gas mask, suggesting that chemical warfare was used during the war participated by Flippy.
The title of the episode is similar to the title of the Dreamworks film Over the Hedge.
The moral means friendships are more likely to be successful when there is a level of space and privacy between the friends.
Aubrey Ankrum's voice was sampled for Fliqpy's voice.
Kenn Navarro's voice is reused for Flippy when he hears the alarm.
There are a few minor differences between the storyboard and the episode. In the storyboard:
Lumpy was going to scream the second the garden flamingos entered his arms, in the episode he waits for a second to react. (This is likely due to the limited animation budget)
Fliqpy is shown running toward the direction of Lumpy after he sees the two flamingos moving behind a fence.
Fliqpy pulls on the cord around Lumpy's head only two times instead of three.
The closing iris closes on Lumpy's head instead of Fliqpy.
