Cuddles is the only crew member in the play who didn't cause the explosion.
This episode makes Disco Bear the eighteenth character to come back to life for another episode.
Russell is the only character whose entire body and face isn't shown. One can only be sure that he was there by seeing his hook holding Giggles' hand near the end of the episode.
While Flaky is falling, The Cursed Idol can be seen sitting on a shelf in the background, on just one frame. It may have been the cause of all of the injuries and the school exploding.
When the characters start holding hands, all three of the female characters are shown holding hands with other characters.
The characters who act and/or direct the school play are the five most frequent HTF characters: Cuddles, Giggles, Toothy, Lumpy and Sniffles (though Petunia is actually the 5th most frequent, with Sniffles being the 6th most frequent) except Nutty. Flaky, The Mole, Lifty, and Shifty are also crew members of the play, as they help with the preparations during the play.
This is the first time both Nutty and Sniffles' deaths are caused by other main characters.
This is considered the darkest episode of the internet series due to the high amount of deaths. The darkest TV episode is Who's to Flame?.
The way Cuddles bounces down the school steps after turning into a bloody cylinder is similar to a slinky.
This is the only time Flippy and Splendid are seen onscreen together at the same time. Splendid flies in at the end while Flippy stabs a Tree Friend.
It is also the only time that they are in an episode together to date.
Cuddles, Giggles, Sniffles, Toothy, Lumpy, Nutty, The Mole, Lifty, Shifty, and Flaky (the tree friends working the play) are the only main characters in this episode to not make background cameos. The other half of the main characters do, however, but not until the fire begins. Petunia is seen screaming during the fire; Disco Bear, Pop, Cub, and Handy (along with some other characters from earlier) are seen injured after the fire; Flippy is seen stabbing a Generic Tree Friend to death while Cro-Marmot is seen standing in the distance; Mime tries to cheer up a Generic Tree Friend with a balloon without success; Splendid is seen flying in when Toothy starts singing; and Russell is seen joining hands with Giggles at the end, seconds before the school explodes.
Some characters are noticeable in the shadows just by shape when they start singing (ex: Lumpy, Handy, Russell, Shifty, Mime, etc).
When Toothy begins singing outside the school, Giggles' eyes on her severed face moves to look at Toothy.
Cuddles weakly raises his hand in the shot featuring The Mole, Pop, and Cub after the fire, signifying that he survived having his face sliced off.
This is one of the many episodes to be remastered for the Blurb version.
This is the only time Splendid physically appears and has an appearance role instead of a starring role. Similarly, this is the only time that Splendid appears but the episode doesn't focus mostly around him (excluding times he appears as merchandise).
Almost every character in this episode suffers at least one injury. The only characters who were not injured at all were Splendid and Cro-Marmot.
When everyone is running from the fire inside the school, Pop can be seen tripping over one of Cuddles' severed ears while holding Cub, and when he falls over, he accidentally drops Cub on the star, which explains how it got on Cub in the first place.
When Handy is shown outside, his feet are ironically enough cut off. The same thing will later occur to him again in By The Seat Of Your Pants.
Flaky would later suffer a similar injury in Let It Slide, where she would drown after her injury.
Cuddles would later suffer a similar death in Ipso Fatso, though in this episode he survives (but later dies in the explosion) and his face remains on top of the cylinder. Sniffles and Handy also suffered similar deaths in Suck It Up and No Time Like the Present, respectively.
One of Cub's injuries involved his fingers getting sliced off. Cub suffered a similar injury in Chip Off the Ol' Block.
According to the staff, they said that they intended to make this episode as special as possible.
The crew has said on the commentary for this episode that they gave Cuddles and Giggles' injuries nicknames. They refer to Giggles' injury as "Pizza Face", while they refer to Cuddles' injury as "Slinky Face."
On the Third Strike DVD, a behind the scenes feature called "Follow the Yellow Rabbit" showed that the school was redesigned multiple times. And for comedic humor, the notes claim that the bell has an engraving that reads "Class of '76 rocks!"
