When the cat is playing with Cuddles' tail, the background music on the DVD version of this episode is different from the Television and YouTube version.
The Cursed Idol makes an appearance when it's dropped from Handy's helicopter. It may have been the cause of Lifty, Shifty, and Russell's deaths.
Cuddles and Lumpy are the only characters who were firemen and didn't kill at least one character.
This is one of the TV episodes to barely focus on the starring character (Mime). Most of the other characters have their own sub-plots within the episode, some of which surpass the amount of overall screen-time Mime has:
Petunia and Giggles attempting to put out the fire only to have both of them set ablaze.
Toothy, Sniffles, and Disco Bear trying to fix the situation.
Pop and Cub's overall screen time.
Handy trying to obtain water to put the fires out, and his later attempt at ejecting from his helicopter.
Lifty and Shifty fighting over Pop's wallet.
The Mole exploring the sewer.
Lifty and Shifty switch roles somewhat in this episodes. Shifty, who usually acts more in charge, would likely beat up Lifty and win, seeing as how he has often sacrificed his brother in previous episodes for his own gain or to save himself from death. This is the only time so far that Lifty has done something similar to Shifty.
This episode features the only instance in the television series, and one of only four instances in the entire series, that Lifty dies before Shifty.
This is one of the few episodes in which all of the featuring and appearing characters die or are presumed dead while the starring character survived.
This is one of the darkest episodes of the TV series and the episode with the third most deaths (behind Wrath of Con and Class Act). Though there were a couple of other episodes with 16 deaths, this one shows almost every death and most of them are separate from one another.
Flippy, Cro-Marmot, and Splendid are the only three characters who didn't appear in this episode, yet they also could have died when the town exploded.
The inspiration for this episode came from a traumatic incident from when Ken Pontac was a toddler. He saw his mother catch on fire while making breakfast because she was talking to his grandmother on the phone and didn't notice that she was next to the stove.
When this episode aired on YouTube along with Easy For You to Sleigh and Wishy Washy, the alternate title for the conglomeration of segments was "Four on the Floor".
According to the commentary on this episode, the writers needed to make a cheat sheet to keep track of the characters that died and how they did.
