The Four is Lava

"The Four is Lava" is the 15th episode of Battle for BFDI and the 46th episode of the overall series. It was released on December 14, 2019.

Before the intro
The episode starts with Gelatin and Flower on a small island that has Cloudy's collection, surrounded by lava. Gelatin tells Flower that there is not enough room on the island. Agreeing with his sentiment, Flower pushes him off instead. Having done so, Flower grabs sunglasses from the collection, puts them on, and crosses her arms.

Meanwhile, Leafy, Needle, Ice Cube, and Taco is sitting on the roof of the restrooms. Taco is still trying to get over the fact that Book saved her and Ice Cube from the lava and sacrificed herself in the previous episode. Ice Cube tries to say something, but Leafy interrupts, saying that Book and Taco should just be friends, but Needle tells her to mind her own business and pushes Leafy, which makes her fall off and glide. However, she is saved by Firey, who does the Four pose. Leafy says that Firey "can't ignore her anymore". Firey is confused, but Leafy, now livid, tells him he knows he still knows her, otherwise he would have not recovered her long ago. Firey instead gets her to safety, dodging her question.

Firey and Leafy, once friends
Once they reach the restrooms, Firey tells Leafy to shut up about him knowing her, because everyone else hates her, and if they know Firey is Leafy's friend, they will hate him, too. Firey, realizing what he just said, shows a look of guilt. Firey dispels Leafy's fears of losing her friendship with Firey, but Leafy tells him the Firey she knew was not like this. A small argument erupts between the two, before Leafy walks away, never to talk to Firey ever again. The Cake at Stake intro plays.

Taking shelter from the lava
The rest of, Dora, Lollipop, Teardrop, Saw, and Gaty, thought dead in the previous episode, are revealed to be alive in an underground hole, thanks to Lollipop's vast amount of Fork Repellent. Every time Lollipop runs out of a can of repellent, the others scream; this begins to irritate her. Saw is fearful, but Gaty reassures her, saying that if they never get out of the hole, they would not be eliminated. Gaty tears up, saying that she doesn't want to get eliminated. One of her tears hits Teardrop, much to her liking.

As Saw's comforting Gaty, Lollipop points out that Dora is lava-proof, and having her talk to Four would get out of their situation. Saw doesn't know, stating that Dora "isn't a good communicator". Lollipop points out that Saw is made of metal, and therefore is lava-proof, too. Saw is afraid her new handle would burn up, but Dora swallows Saw's top. They both swim to the surface, the first set of recommended characters beside them.

Saw asks Four to get out of the lava, to no avail; Dora, though, successfully asks Four (initially a recommended character named the "Four Statue") to do so. Four uses a magma hand to pick up the ers stuck in the hole, and Taco and Ice Cube, and send them over the second set of recommended characters into Cake at Stake.

Cake at Stake
Saw and the other ers express surprise at Taco's survival, and apologize for how they treated her in the past few episodes. Taco smiles, albeit slightly. Gaty realizes that they are missing one, Book. Taco asks Four to recover Book, and the other ers express surprise at this, given her interactions with Book.

Five pairs of arms come out Four's mouth, to the other ers' surprise, but Four immediately swallows and recovers Book, who lands next to Taco. Taco is about to say something until she is interrupted by Four, who starts Cake at Stake.

The cakes to be given out are happy thoughts:
 * Ice Cube's is Pencil, Match, Leafy and Book being set on fire; a giant Ice Cube says "Revenge!"
 * Teardrop's is shattering things, and Pillow, with a hammer. A recommended character, "shatter sound", can be heard.
 * Saw's is her skipping in a field, exhuming 8-Ball's Fumes and losing her tendency to say "eight".
 * Taco's is a flashback of the previous episode of Book saving her and Ice Cube from lava (Taco comments that it isn't "really happy" and confusing to her; Four tells her she should get over it)
 * Gaty's is Four telling her she is safe, over and over again (representing her fear of elimination being quelled)
 * Lollipop’s is a flashback to BFB 8 of Donut repeatedly saying “Bagel Brain”.

It is down to Lollipop, Dora and Book; the latter is safe. Book's happy thought is the Cake at Stake in "Reveal Novum" with her definition and the Announcer "giving" her Dream Island, complete with the music that played when TV was "given" Dream Island. Book says she likes this show.

Lollipop and Dora are left. Book wishes for Lollipop to be safe, but the latter only mutters. Lollipop is safe, and her happy thought is Donut on TV repeatedly saying "bagel brain". Lollipop laughs at this, while Dora gives a speech:

Of course. It's as I feared. An island eater such as myself has always been fated to go hungry. As I starve, trapped in the depths of this number's wretched, squishy body, my final thought will be that of the time I've spent with you all. If only I could stay for just one moment longer, perhaps I would reveal-

...until Four interrupts her, telling her to stop being "dramatic". Dora is sucked into Four, and lands inside the vast space between her and the door to Eternal Algebra Class Withfour. She enters EXIT.

Death P.A.C.T. inside Four
Bottle, Pen and Remote play around with Four's mouth in The Fourest - the cause of the arms sticking out of Four's mouth. As Pillow walks off, Tree tells Black Hole that this is a waste of time, and that they should really be looking for a way out. Pillow is fascinated by Bracelety's signs, which trail all the way into the entrance to EXIT.

Meanwhile, Book is sad about Dora's elimination, but Gaty does not want to talk to Book. Four attempts to announce the next contest, but is interrupted by the arms, and Gaty telling him that everyone alive is scattered, and that he should speak louder to make his voice heard by everyone. His voice is indeed heard by everyone, to the point it can be heard from space, inhabited by a ring of recommended characters, Spongy (in his private jet) and Puffball.

The Challenge
X jumps out of the lava into the air and points down at Four, serving as a pinpoint for the challenge. Four commences the challenge, stating the last team to arrive where he is will be up for elimination. Much to Four's surprise, finishes first as they are already at the Cake at Stake place.

Meanwhile, Firey attempts to convince Leafy to get down from the bathroom roof and do the contest, but Leafy refuses, arguing that if their team loses, Firey will get voted off. The two argue for a bit before Needle loudly interrupts them before pushing Leafy off in order to get her to do the challenge. Firey manages to catch her, and the three begin making their way through the lava towards Four.

Spongy fires a cannonball at Puffball, almost knocking her over. She angrily tells him to stop shooting at her, but Spongy refuses before shooting many cannonballs at her, and Puffball dodging them in a pattern similar to the one used in in Lofty, Gardening Hero, and Get Digging. She then notices Foldy and Bell, the two other alive members of Free Food. She uses Bell in order to deflect one of Spongy's cannonballs back into his own ship, and the two, along with Foldy, who had landed back on Puffball's head, begin to make their way to Four.

Meanwhile, Taco attempts to reason with Book. However, they are interrupted by Four, who has had enough of Death P.A.C.T. So he pushes Pen, Bottle, and Remote off of the tree they were using. Pen notices that Pillow is attempting to enter the E.X.I.T. Four then grabs all of Death P.A.C.T., including Pillow, and pulls them out of his mouth onto a nearby cliff. He then gives them a menacing look and states that they are safe.
