"The Great Mushroom War Part I"
"The Great Mushroom War Part II" is the second episode in the first season of CamDog and ACat's episodes. It is the second episode overall.
Princess Bubblegum and Marceline meet for the first time in the second half of this two-part episode.
- Princess Bubblegum
- Uncle Gumbald
- Luna Abadeer (in recap)
- Shoko (corpse)
- Simon/Ice King
- Hunson Abadeer (mentioned, in back-story)
- Vampires (in back-story)
- Vampire King (mentioned, in back-story)
- This episode is a continuation of "The Great Mushroom War Part I".
- This episode does not have the normal theme song because Finn and Jake are not in this episode.
- This episode takes place 815 years ago (before Ooo), as opposed to the previous one, which takes place 998 years ago. This means that Ash is also much older than he looks, similar to Maja, Marceline, and Princess Bubblegum.
- The episode has several scenes from "Memory of a Memory".
- Princess Bubblegum is her thirteen-year-old self at the start of this episode, though on Adventure Time she is 827, not 828. This is because, according to ACat, the CamDog and ACat's episodes take place two years after the early season five and one year after the current episodes. However, this is subject to change depending on what happens in the future of the show.
- Unlike the other early Candy People, Princess Bubblegum started out as a baby and continued to age until she injected herself with the candy stabilizer at the age of 18. This is because she has human DNA in her, most likely from when Simon made physical contact with the pink goo in "Simon and Marcy". It is also revealed that the goo from that same episode was actually the early Candy People, or Bubblegum People, in their early stages of development.
- This episode reveals that Uncle Gumbald is actually just Princess Bubblegum's "geological uncle", meaning that he originated in the same place as her direct predecessors or "parents". It is also revealed in this episode that he created the Candy Kingdom and then crowned Bonnibel as the princess and ruler of it, contradicting Finn's statement in "All Your Fault" that "[Princess Bubblegum] built a whole kingdom out of candy", though she probably played a major role in its creation and made most of the inhabitants.
- Uncle Gumbald chops down all the trees in the area where Finn and Jake found Susan Strong in this episode, just like Princess Bubblegum said he did.
- Maja starts to introduce herself to Ash as Betty before stopping herself, hinting that the two are the same person, though this will not be proven until "Something Big".
- Princess Bubblegum receives the rock shirt as a birthday gift in this episode. Shortly after, she takes a picture with Marceline, the same one that is seen in her closet in "Sky Witch".
- Marceline goes rabid when she finds out that Ash sold Hambo, similar to how she did in "Red Starved" when not having any red to eat. While rabid, she tries to suck the pink from Princess Bubblegum's face, just like what she did in that episode and what is mentioned in her song in "What Was Missing".
