Don't Dig Straight Down

"Don't Dig Straight Down" is the 14th episode of Battle for BFDI, and the 45th episode of the overall series. It was released on August 24-25, 2019,

The episode is a continuation of the original 13th episode of Battle for BFDI, "Return of the Rocket Ship".

Plot
This episode continues off after the events of "Return of the Rocket Ship", when members of Team Ice Cube! discover an unknown location underground. After a bright flash of light, it is revealed that they stumbled upon an Inverted Planet. Donut tells the team that he's heard stories about them, but never knew they lived so close to one. Gelatin and Naily immediately start running around, chasing each other. They jump off of a tree, and Naily impales Barf Bag as she lands, spilling her barf everywhere. Donut begins to worry and tries to patch her up when she starts to feel sick, and tells the two of them to stop running around.

Iance is then seen walking through the tunnel they're digging, and Ruby tells Flower she's mad that she killed Bubble. The two squabble before Lightning questions the direction that they're digging in. Ruby agrees and starts to dig at Grassy's co-ordinates with Flower's help.

Votes
The previous episode was a non-elimination episode, so the viewers voted for their favorite characters. The results have yet to come out.

Preview transcript
A 10-second preview was shown during the 2019 Crossover Meetup, whose transcript is shown below.

Continuity references

 * Golf Ball's Underground Factory, which first appeared in "Zeeky Boogy Doog", reappears.
 * Gelatin after sitting on top of Bomby with Barf Bag and Naily, he said "there isn't enough room up here" and pushing Naily after exploding, which is a reference to BFDIA. Gelatin would say this catchphrase on top of Puffball before he pushed his teammates.
 * Naily saying she's sorry for stabbing Woody 7 years ago is a reference to The Reveal.
 * Woody falling from the garbage chute and into Four’s eye has a reference to BFDI APPISIOTE 225555555!!!!!.

Cultural references

 * The title of the episode is a reference to Minecraft, where all Minecraft players warn everyone to not dig straight down due to Lava being underground.

Trivia

 * The episode continues from where the previous episode, "Return of the Rocket Ship", left off.
 * This is the reason why this episode did not have a Cake at Stake.
 * Two new animators join the show: Joesph Park and Allen Lee.
 * According to Cary's and Michael's reaction to BFB 13, Michael will be animating this episode, and Cary will be doing more than writing.
 * This proved to be true, as Cary animated part of the scene with Free Food.
 * A short preview was shown during the 2019 Crossover Meetup. It was a scene of Golf Ball and Tennis Ball talking about how warm it is, and was a 10-second loop.
 * The episode was initially set to release on August 7th, 2019, but was pushed back a week due to Satomi flying to New York and some paperwork issues.
 * The episode was moved to release on August 14th, 2019, but has been pushed to August 24th, 2019 due to Michael's apartment being fumigated for a cockroach infestation.
 * Barf Bag starts the intro this episode.
 * As of this episode, she is the first BFB contestant to start the intro more than once.
 * Characters that have no speaking cues are Gaty, Teardrop, Saw, Dora, Ice Cube, Bell, Eraser and Rocky.
 * In addition to that, Firey, Clock, Eggy, Leafy, Bubble, Pillow, Pie, Bottle, Black Hole, Remote and Tree didn't appear. However, the contestants on Death P.A.C.T. with arms were shown to grab the emerald.
 * Pen was the only Death P.A.C.T. member to appear physically, as the other had their arms shown.
 * Even though he didn't appear, it's possible that Firey survived the lava, since he's immune to any heat source.
 * This episode marks the first time that is up for elimination.
 * Out of all the Battle for BFDI episodes, this episode has the most deaths, with 120 (including the recommended characters and if Saw and Dora didn't die; they were both shown to survive lava in "Getting Teardrop to Talk").
 * The majority of the objects that didn't take shelter, such as Barf Bag, all of iance and the recommended characters, or sacrificed themselves, such as Bomby, Book, Cake and Naily, died in the first lava geyser or eventually died later due to exposure to lava.
 * The number of contestants that died in this episode total 36 - a rate of 1.5 contestant deaths per minute.
 * Spongy, Puffball, Woody, Taco, every member of Death P.A.C.T., and presumably Firey and Ice Cube, were the only contestants to survive the events of this episode.
