The opening sequence is different from all the other Halloween episodes. Instead of having everything more dark and Gothic, it opens up like a normal Internet episode. Halfway through the opening title, however, the screen goes fuzzy and turns to static. Then a picture, which resembles a 50s Sci-Fi horror movie poster with the starring and featuring roles at the bottom, pops up with 50s Sci-Fi horror music accompanying it. The closing credits are also different with different music.
If you look closely, at the end of the episode, one of the Pod Lumpys acting as a car is wearing an air freshener necklace (similar to Petunia's, but blue).
This episode doesn't appear in the Halloween Mini site of Happy Tree Friends.
This is the first season 3 episode to end up with there being more dead characters than living.
Nobody dies until three minutes into this episode.
This is the last episode produced in 4:3 resolution. In the next episode Wrath of Con and further episodes, episodes are produced in 16:9 resolution.
This is one of the three episodes to go over 5 minutes (however, it is the only one of those three to be less than seven minutes). The other two are From A to Zoo and A Sucker for Love.
According to the Blurb version, there was a deleted scene in which Cuddles kills one of the Pod Lumpys, whom seems to be a janitor with a mop. It's possible that this was put in as a joke.
The YouTube thumbnail for Blurb version spoils Petunia's injury.
This is the only Halloween episode that does not involve a dark environment.
The title of this episode is a snippet of the saying "two peas in a pod," which means to describe two people behaving the exact same.
In the closing credits, "Alan Smithee" is credited for doing the animation for this episode. This is a joke, as Alan Smithee was a pseudonym used by dissatisfied directors who wished to disown their films.
Lumpy using many clones who break into two different entities upon having a part of their body being cut off to do his chores may be a reference to The Sorcerer's Apprentice, most famously recognized from the Disney film Fantasia.
A similar event happened on The Simpsons Halloween Special 13, in a segment titled Send in the Clones, where Homer uses a magic hammock to clone himself and makes the clones do odd jobs for him. The clones begin to kill people instead of do chores and they take over the town, much like the clones in this episode.
