"Be More" is the twenty-eighth episode in the fifth season of Adventure Time. It's the one hundred and thirty-second episode overall.
The episode starts with BMO hiding under a box. BMO brings up a file manager interface on its screen, and drags and deletes files. BMO seems to enjoy this, though it also seems to make it a little weak. BMO repeats this process, but accidentally selects and deletes coresystemdrivers.sys. Deleting this crucial program causes BMO to collapse.
BMO wakes up to see that Finn and Jake had found BMO and propped it up on some pillows. BMO, stuttering, explains that it needs to install new core system drivers, which they can find at the MO factory in the Bad Lands, where BMO was born. BMO leads Finn and Jake there, but warns them that damaged MOs get a full memory wipe before they are repaired, and Finn and Jake assure it they will not let that happen. BMO then explains that only MOs are allowed in the factory. Jake shape-shifts into a MO, and Finn pretends to be a MO by stuffing his head and arms into his shirt, exposing his stomach, placing BMO on his head to be the head. While Jake pretends to be JMO, Finn pretends to be FMO.
Finn and Jake request new core system drivers from the robotic MO factory receptionist. The MO receptionist then tells "FMO" to prepare for a full memory wipe. Finn backtracks, claiming that they had only visited the factory for nostalgic purposes. The receptionist then leads them on a complementary factory tour on a tram. On the tour, Finn, Jake and BMO spy the driver ports through which BMO can download its core system drivers. They jump off the tram, only to find that the B port (the only port compatible with BMO) is not there. The factory's security guards appear and shoot their vaporization guns at the three, who dodge out of the way just in time. Mistakenly believing that they have successfully vaporized the intruders, the guards leave.
The guards return to a staff lounge for small talk. Jake shape-shifts into one of them, carrying Finn and BMO on his shoulders. BMO explains that if it can connect to one of the guards' ports, it can hack into its computer and find where the B port is. Jake plugs BMO into one of the guards, recovering a map to the B port, and then the three leap out of Jake's disguise. They re-board the tram, with the security guards in hot pursuit. They follow the map to the B port, falling off the tram and crashing through several floors before landing.
The security guards fall soon after, brandishing their vaporization guns at the three, before BMO explains, "I am not non-MO. I am BMO." The guards gasp, and a voice asks, "BMO? Did I hear 'BMO'?" Finn, Jake and BMO look up to see an emaciated, atrophied old man, kept alive only by MOs. The man explains that he is Moe, the creator of the factory, as well as the creator of BMO. Moe assures Finn and Jake that he will not reset BMO's personality. Moe explains that he originally built BMO to take care of his son, but since he never had a son, he sent BMO off into the world alone, hoping that it could find a family of its own, maybe even find somebody else's little boy to take care of. Although he claims to have built a million robots, Moe says that BMO is very special: he built BMO to understand fun and how to play. He built BMO to be more—this is BMO's namesake. CMO hands Moe a back-up drive disk, which heals BMO. BMO awakens and runs up to hug Moe. Jake points out that although Moe claimed to have made millions of robots, he and Finn had only seen the receptionist and the security guards, and calls them jerks. Moe then leads them to a hatch, which opens to reveal a populous and diverse ecosystem of robots. Moe tells BMO to say hi to its family, and BMO immediately does. The other MOs say hi back to BMO, and BMO slaps its screen in happiness. The episode ends here.
- This is the first appearance of BMO's creator Moe.
- In the Tree Fort, a nuclear bomb can be seen on the shelf.
- It is revealed that out of all the MO bots, BMO is "one-of-a-kind." BMO means "Be More" which is the title of the episode.
- BMO contains Windows ".exe" program files and Mac ".dmg" application disk images, indicating that it can use both.
- CORE SYSTEM DRIVERS.sys with a MSDOS/Windows file ending appears to be the only file deleted that is critical for BMO to keep functioning normally.
- Furthermore, the various MOs can read .MO files, as seen when BMO is downloading the map of the facility.
- When Finn and Jake fall through the factory floors, they pass a purple bed emblazoned "AMO" on the front. They also fall past the BMO port.
- When Finn jumps into the room with the MO ports, the port for AMO is somewhat visible, it appears to have the same general shape as BMO, but is larger, with no arms, a wider section on top, and seems to have two sideways horns protruding from both sides.
- BMO can be turned on by pressing the up on the D-pad and the triangle button.
- When Finn, Jake and BMO are on the final level, CMO makes another cameo appearance, handing BMOs backup driver disk to Mo.
- BMO has a literal heart of gold.
- A MO named LMO is holding a one dollar bill that has a face of a skull which appears to have broken horns attached to it.
- The second floor Finn, Jake, and BMO crash through is where the Snail is located in this episode.
- It has been stated by Pendleton Ward that Moe is not a human because he has been wasting away and bit by bit replaced his organs and body parts with electronics, making him a cyborg or even robot.
- In 2014, this episode was nominated for the Primetime Emmy Award for Outstanding Short-format Animated Program.
- In the chapter "Be More" AMO's room who is the antagonist of the chapters "The More You Moe The Moe You Know (Part I)" and "The More You Moe The Moe You Know (Part II)" appears .
- BMO's interface is similar to an Apple computer's.
- One of the files BMO has is command.electricslide.exe, a reference to the popular dance the Electric Slide.
- Another of BMO's files is controls.brownnote.sys, a reference to the hypothetical tone that would cause humans to move their bowels.
- When Moe re-powered up BMO after fixing it, the old Apple start-up chime plays.
- This also happened when BMO had its batteries re-inserted in "BMO Lost."
- The stone slabs in the title card slightly resemble Stonehenge.
- When Moe opens BMO's case, among its innards are a diploma, a heart, and a medal. These are also the gifts given to the Scarecrow, Tin Man, and Lion in the 1939 film The Wizard of Oz.
- The first room Finn, Jake, and BMO fall into after the tram chase appears to be an old cleaning supplies room, which has a caution sign that reads アブナイ, which means 'dangerous' in Japanese.
- While SMOs are going after Finn, Jake and BMO, They go through a Corkscrew, which is one of the famous Roller coaster elements.
- BMO states that if his memory is wiped, all the memories will vanish like tears in the oven. This is a quote from the film Blade Runner, though BMO says it incorrectly. It should say that the memories vanish like tears in the rain.
- In falling from the tram scene there is a deactivated MO that resembles the original Game Boy Advance models in the AMO room. A tank for a small reptile or mammal is also in the room.
- "Be More" is the slogan for PBS.
- Moe's design is based on the famous Arab-American actor Jamie Farr.
- This is the first episode in which Finn definitively finds someone who is at least close to human, Moe (who is kept alive only by robots). Moe could be one of the survivors of the Mushroom War, after Ice King, as DMO states that Mo Co. "was founded over one thousand years ago by Moseph Mastro Giovanni" (Moe).
- Moe explains that he originally built BMO to take care of his son, but he never dated and so never had a son. AMOs room, which is the third room Finn and Jake fall through, looks much like a human boys room. This could be showing that AMO took the place of a son, or already having a son, in AMO, he never got around to dating, though he planned on it.
- Pendleton Ward sent Aziz Ansari a last-minute tweet asking him to be in this episode.
- Both Rebecca Sugar and Patrick McHale helped write the episode when it was originally pitched during season 3. Both had left the series by the time the episode had actually gone into production, however (Sugar left after boarding "Simon & Marcy" and McHale left after helping to outline "The Suitor").
- The episode originally ended with Moe telling Finn, Jake, and BMO that they needed to leave because he needed to use the toilet.
- Additionally, the scene where Jake pretends to be an SMO originally had Finn in the SMO's body, using his stomach as a face.
- When Moe puts back BMO's motherboard, the screws disappear and are never screwed back in.
- Moe uses a Phillips head screwdriver to remove the slotted head screws holding on BMO's circuit board.
- The directions, as Finn repeats to himself, to get from the SMO break room to the ""B"MO Driver Chamber" are down, right, left, down, corkscrew, down. While traveling to the chamber/running from the SMOs, Finn only gives the directions: down, right, left, corkscrew, down, missing the second "down" direction.
- The cable that Finn uses to connect BMO to the back of SMO is in the same place where BMO's Main Brain Game Frame access button should be.
