Trivia

 * This episode reveals that the time Cuber lives in is far in the future than the current time in "Adventure Time," and that he comes from a planet outside of Earth.
 * Marceline may still be alive in the future because Cuber was seen at a very similar house to Marceline's house and music is heard playing.
 * Although it wasn't clearly confirmed, the house in the cave is most likely to be Marceline's house, as several parts match with the original one, like the amount of floors, the drapes and a support where the basketball basket would be placed.
 * The new Marceline's house has a candy-shaped decoration in the side door that does not appear in the original house.
 * The Ice Kingdom in the future seems to have a new ruler meaning Ice King had died or was cured by Betty and his crown fell into someone else's hands.
 * A new form of a Gumball Guardian is seen and it seems to now be part of a mobile Candy Kingdom, likely created due to the kingdom's abandonment as seen in "Lemonhope Part 2". In the Guardian, Candy People from the current time in "Adventure Time" are seen, suggesting that the event that led to their placement into it maybe sometime fairly soon.
 * When Cuber and the aliens are being transported inside the Gumball Guardian, a picture of the former Candy Kingdom can be seen on the left wall.
 * Many of the furniture usually seen in the Tree Fort can be found on the future Marceline's house.
 * In a scene from one of Cuber's Graybles, Jake picks up the thought cannon and says "Bobble Bobble". When Cuber later digs up the thought cannon, he states "Bobble Bobble, as the dead might say". This confirms that Jake dies sometime between this episode and the present Adventure Time timeline.
 * The Ice Thing has only two of the three original gems from the crown attached to its body. The rightmost gem is missing.
 * When Cuber returns to the spaceship and walks along the hall while talking, a being similar to Tuber, but red, can be seen in the last picture.

Episode connections

 * This is the the fourth Graybles episode. This means so far there has been at least one Graybles episode every season since season 4 starting with season 4's "Five Short Graybles" and season 5's "Five More Short Graybles" and "Another Five More Short Graybles."
 * This is Cuber's fourth appearance over the show.
 * Cuber is seen far in the future at Finn and Jake's Tree Fort which looks very similar to the future seen in "Lemonhope Part 2."
 * Princess Bubblegum is seen spying on the candy people in this episode meaning her change from "The Cooler" and "The Pajama War" went away after the events of the latter.
 * However, she is seen wearing the same t-shirt she wore in "Jake The Brick," implying that the events about her and Starchy might had taken place in the same episode.
 * A grave of Starchy can be seen near the Grass Lard in the future and in one of the storyboards, it was written: "In memorium of Starchy 1, eaten by a Grass Lard. He loved to walk." This implies that Princess Bubblegum had made a clone of Starchy and that the Starchy that had appeared in later episodes after "Jake The Brick" might had been his clone.
 * In the hole Cuber dug up to find Finn & Jake's wand, the golden bone from "Ocarina" can be seen.

Storyline analysis

 * Despite what seemed like a breakthrough for Princess Bubblegum in her obsessive monitoring of the Candy Kingdom in "The Cooler", this episode shows she has switched to even worse tracking methods; further if the future where the Graybles stories is true, then by then her security power has reached the point of using Gumball Guardians to capture anyone who even tries to escape. However, it was also implied that she might not had done this by force as in one of the storyboards, Crunchy asked, "Did it work?" and that the events may had taken place in "Jake the Brick" as she is shown wearing the same t-shirt in the episode.
 * Near the end of the episode, there is a quick shot of a destroyed Ice Kingdom with an even quicker shot of a flying beard with Ice King's crowns' gems. As this episode was set 1,000 years after the timeline of Adventure Time, this suggests that either Betty was unable to save Simon from the crown's power and he transformed into a flying beard with the crown fully in control, or the crown was transferred to another being who took on facets of the Ice King and/or Evergreen.

Errors

 * After Cuber had returned to his spaceship, pictures of the events that had taken place in his graybles were shown. In one of the pictures, Princess Bubblegum is shown looking at her laptop like how she was in the episode but was wearing her regular outfit instead of her t-shirt.
