1. The petrol station in "Bonnibel Bubblegum" is where PBs past life used to work[]
This is why PB was drawn to it. And the picture of the family is the past Candy elemtal as a kid with his parents.
2. The Mother Gum is a mutant version of the past CE[]
After the war alot of people and other creatures ended up mutanted by radiantion. The past CE was also mutated, but because he's an elemental it affected him differently and he ended up a big mass of semi-sentiant gum.
So not only is PB a reincarnation but her and Neddy also formed from his remains.
3. Shelby and Kent are Candy People[]
He looks different to the other talking worms in the show, And Kent looks nothing like a worm at all (but does look like a gum drop).
Mabey Shelby was sent by PB to keep tabs on Finn and Jake after they became her knights, but even after these years Shelby stayed at the Tree Fort as a roommate.
4. PBs swan is a robot/cyborg[]
Because it has lasers and was kept under a sheet in "Bonnie and Neddy".
5. Tree Trunks and Mr. Pig are Candy People[]
Nothing to back this up realy. It was inspired by this edit. That and the fact that a pig similar to Mr. Pig is seen in "Scamps".
Edit: this has been disproven by "Ring of Fire"
6. The Pods where created by PB[]
Again. This is just completly out of nowhere, and is more fanfiction then a theory. The good pod made ice cream.
Mabey PB made the pig and wand pods to make soilders, but they turned out bad so she had the last two remaing pig and wand pods locked away but also made the ice cream pod to be safe.
The gnome knight was either a volunteer or was made to guard the pods as punishment for missdeeds (the other gnomes we've seen are bad).
7. PBs crown gem and earrings are made from the Finn comet[]
The Lich is an incarnation of a prehistoric Comet similar to how Finn is to the blue comet. This is why the jewles have the power to block the Liches infuence.
Also Finn is the only person to risist the Liches mind control without the Gem (since it got smashed) implying that anything related to the Comet can resist the Liches power.
