Trivia

 * In the extended preview, Abraham Lincoln can be seen with the Lord of Evil in a picture.
 * There is a picture seen in the long preview. It shows Marceline as a child standing next to her father on the left and another woman standing in the right who has a striking resemblance to Marceline. This may possibly be her mother, but this has not been proven.

Episode connections

 * Finn's new sword which he got in the episode Dad's Dungeon will return in this episode.

Production notes

 * This episode was previously titled "They Went to the Nightosphere," and was renamed. The current title was used as a former title for the episode "It Came from the Nightosphere."
 * This will be part one of a two-part episode. This two-parter will be shown at once on the 30th of April. This episode will be paired with "Daddy's Little Monster".
 * This is the third two-part episode, the first being "Mortal Folly" and "Mortal Recoil" and the second being "Holly Jolly Secrets Part I" and "Holly Jolly Secrets Part II". (Althought "Hot to the Touch" is a continuation of "Incendium", they weren't aired neither in the same day, nor in the same season).
 * Most of the monsters were designed by Andy Ristaino
 * This is the first half-hour episode to appear within the first month of the season premiere.
 * The hair style that Marceline wears is the same to It Came From the Nightosphere, which is coincidental because Marceline's father was in that and this episode
 * It says on the T.V. guide that it is They Went to the Nightosphere instead of the current title.
