Princess Bonnieball Bubblegum

It was a perfectly normal day, the weather was calm, and Snezhnyay wasn't attacking anyone. Finn and Jake decided to throw a movie party at their house. Princess Bonniebelle Bubblegum, Marceline, Princess Lioncorn, and Lumpy Space Princess came. The movie was about the Mushroom Wars—an adaptation of survivors' records from that time. There were tears, drama, romance, death, loss, fights, carnage, famine, civil wars, and... well, everything that happens after a nuclear war or a war between survivors.
Bonnie occasionally glanced sideways at Marceline, still bitter about that incident years ago in the Glass Kingdom. She still remembered that breakup song, filled with toxicity, malice, and bitterness that had driven the magma dragon into the Glass Kingdom's dungeons for years.
Marceline, in turn, teased the princess, trolling her with taunts and also casting sideways glances at Bonnie. Marceline was still hurt by Bonnie's words about Marcie acting like a terrible monster... just like she'd been afraid to consider herself as a child.

There is a rift and a fight between Princess Bubblegum and the Vampire Queen.
