|This article is about Princess Bubblegum's parent. You may be looking for the gum mass from the comic series.|
The Mother Gum is a collection of living beings made of mutated bubblegum. First seen in "Simon & Marcy" as being scattered around the bombed-out surface area, sticking to mutants or humanoids, and giving the tools to Simon Petrikov he needed to feed Marceline chicken soup, not much is known about the Gum Hive's origins.
In the game Adventure Time: Explore the Dungeon Because I DON’T KNOW! the Mother Gum is hidden underneath the Candy Kingdom. Princess Bubblegum explains that the hive gestated her about a thousand years ago and blasted her out 827 years ago. She'd been protecting them there ever since.
Continuing with the events of the game, the Hive had seeped through the dungeon walls of the Candy Kingdom and accidentally released prisoners, leading Princess Bubblegum to send fighters to take them down and investigate the cause. She had realized too late that the Gum Hive was the cause, and tried to prevent the fighters from destroying it, but it was too late. The Gum Hive became unstable and dissolved as bubbles, and were eventually into the skies of Ooo after they were defeated.
- In "Bonnie and Neddy," when Princess Bubblegum dropped from the Mother Gum, she waves and speaks to it in clicking noises indicating that they have some sort of unique method of communication.
- In the video game Adventure Time: Explore the Dungeon Because I DON'T KNOW!, Princess Bubblegum explains that she was part of a sentient pink goo that was formed about one thousand years ago, and achieved sentience upon being spat out. This substance is very similar to the "Mother Gum," and the basis of the game's information seems to coincide with the show.
