This episode marks the second appearance of The Blue Hen (Mental Hen) making her an established antagonist in the series, she might not appear again unless she can escape her ice prison.
Skipper is strong enough to break through solid ice even when he is frozen in it.
During the training sequence at the beginning of the episode, one of the penguins jumps through a flaming hoop. This may be a reference to Vitaly's storyline in the third movie.
This is the first time Skipper talks and dresses like a hippie, also it's the second time a penguin was a hippie, the first penguin was Rico in Hello, Dollface.
This is the second time Kowalski attempted to do the Kowalski, but this time it failed, though the hen was seduced for only a few seconds when Kowalski said "Is that so, beautiful chicken lady."
Kowalski describes his ability to prepare for unforeseen and outrageous scenarios with the Internet meme "like a boss". Which is quite true, both literally and figuratively.
Kowalski's become a much better (and more gung-ho) leader since previous episodes such as Command Crisis, but as it turns out most of it was rigged by the Blue Hen.
The hen chose to be senator of Delaware this time than president.
Strangely, the penguins can still retain the ability to move, but lack speech and can still see and hear things around them, such as Skipper breaking his cubes and Kowalski's eyebrows making a V shape when Skipper said Kowalski would never be as great a leader.
The hen said, "Did you really think someone is dumb enough to get trapped in a bell by their own." to which Kowalski responded, "IT WAS JULIEN!" So apparently, Kowalski thought Julian was dumb enough to get himself in the most impossible and wild predicaments.
This is the second episode to have an acronym in the title that's mentioned in the episode, the first was the Big Stank.
P.E.L.T. is an abbreviation for "Physical Endurance Leadership Test", just like S.T.A.N.K. is the abbreviation for "Super Toxic Aeronautic Kaboom-boom".
The Super Blimp is mentioned again as: Scenario 1: Super Blimp Sneak Attack, the first mention was In the Line of Doody.
Fred is revealed to be too weak to rattle his own tree like Skipper had.
One of the scenarios in Commander Kowalski's scenario binder involves a (rare) heavily-armed manatee assault team.
In Step Two of P.E.L.T., Skipper had said: "Step Two, provoke and evade a polar predator." The polar bear he provoked was Ted.
