Mr. Coffee - When Timmy was searching enemies in the kitchen, he opens a drawer and a Coffee Machine inside it has written "Coffee Guy" on it; this is likely a reference to the coffee machine trademark, Mr. Coffee.
Albert Einstein - After the spaceship was sucked in the black hole, Crocker says "Einstein was right, Black Holes lead to Bakersfield.", this is a reference to Albert Einstein with his theories about Black Holes and Albert's first cousin 2x removed, Han Einstein, who was a physician that lived in Bakersfield, California and/or the company, Einstein Computer Services which is located in Bakersfield, California.
Foop, Mr. Crocker, and Dark Laser keep getting attacked by bears.
Mr. Turner auditioning for clubs such as sewing, lumber jack and sky diving.
Villains getting their legs chopped off and saying, "Thank goodness my legs were asleep/sore, otherwise, that would have hurt like the dickens."
Cosmo spilling his chocolate milk.
Cosmo trying to say why people eat something on a certain day.
Foop/Dark Laser applauding Vicky while looking at her, causing Vicky to yell "THE EYES!" in return.
Villains saying it was worth waiting somewhere for 6 months to get Timmy.
Cosmo, Wanda and Poof were shown floating while the Fairyclipse was still going on. The same thing happens with Foop.
Mr. Crocker does not try to get Foop, even though he is trying to prove the existence of Fairies and Foop is an Anti-Fairy, which is almost the same thing.
This could be because Crocker doesn't know what an Anti-Fairy is and/or looks like. This was shown in Timmy's Secret Wish.
Unlike other episodes, Vicky refused to get paid by the losers, which contradicts her greedy self.
Mr. Crocker, Foop and Dark Laser had their legs chewed off but were completely fine afterwards. Later on, the trio along with Vicky were destroyed by the laser but again were fine afterwards.
It's possible that Timmy merely wished for them to be incapacitated and not destroyed. In the episode "Dread 'N' Breakfast", when Dark Laser was incinerated, Timmy said "Whoa, too far!", and had Wanda bring him back.
The ship's Dark Laser face was wider while the L.O.S.E.R.S. were grabbing Timmy off to throw him in the black hole, but later in space the face was smaller.
Vicky got a job at the Cake and Bacon, even though she couldn't find a job in "Vicky Gets Fired!".
Why did Timmy's dad join the sewing club when he had a sewing room in Micecapades?
It is possible that Mr. Turner isn't good at sewing (which is shown in the episode).
When the episode starts, it says the starting events took place 24 hours earlier before Timmy got attacked with the laser. This is not possible since two nights and two days got passed when the events first started and ended with Dark Laser (as Timmy) getting attacked.
Timmy says the Fairyclipse ends at midnight, but it appears to be during the day when that happens.
Of course, time zones mean that it's midnight elsewhere on Earth
When Foop says "It's a good thing those fire ants numbed my legs with their venom, otherwise that would've hurt like the dickens.", the captions display the D in NUMBED as an R, as if the fire ants number Foop's legs. How can things always number people's legs?
On many occasions when Timmy frowned his buck teeth weren't there.
Foop doesn't want to destroy Poof in this episode, only destroy Timmy.
Foop says he would high five but his arms were too short, yet in previous episodes he managed to do that (and called it a high four instead).
