This is a list of confirmed events between the latest episode of a season and the next season.
Confirmed events between BFDIA 20 and IDFB 1[]
- Firey, Woody, and Bubble are recovered.
- Golf Ball, Nickel, Bomby, Rocky, and Yellow Face stop being possessed by Evil Leafy.
- Fries, Gelatin, Pencil and Ice Cube leave the tornado.
- Bomby loses his purple color.
- All of the LOLers stop being taped up. Firey Jr. also gets out of Bottle.
- There are no eliminated contestants rejoining, at least not from the TLC, as the eliminated contestants sent to it are still there as of IDFB 1.
- Ice Cube willingly goes back to Yoyleland.
- The hole next to the HPRC gets patched up.
- The FreeSmart SuperVan is placed in front of the HPRC with glue coming out the exhaust.
- FreeSmart does something related to the Science Museum that Needle keeps a secret.
- The stairs of the Yoyle Needy are fixed, after being out of order as of BFDIA 6.
- Pencil falls off the Yoyle Needy at least once, as implied by Book.
- Firey gets trapped in a cage hanging from the top of the Yoyle Needy by FreeSmart, possibly as punishment for recovering Leafy.
- All but one of Fries' fries are destroyed either by rotting away, Firey burning them, or Gelatin eating them.
- He has already lost his fries from Gelatin eating them in various episodes, and them rotting away in BFDIA 18. However, he was recovered and regained them both times.
- Tennis Ball invents Grotatoes for Fries to use to replace his fries due to Yoyle City not being sunny enough for normal potatoes to grow.
- Pin becomes friends with Coiny again and abandons her sadistic and competitive personality.
- Pin loses her color, as the red pigment in her body was extracted and restructured into new limbs by Golf Ball. As a result, she also loses her Mech Suit, battery, and drill.
This likely happens in an episode that takes place around March 2016, as it was stated to happen about 6 months ago in IDFB 1.
- Nickel is unaware of this happening until IDFB 1, most likely due to him being in the WTF.
- FreeSmart continues to record audio-only diaries until IDFB 1 due to Ruby never removing the lens cap from the Camera. They also continue to collect gumdrops.
Confirmed events between IDFB 1 and BFB 1[]
- Everyone moves from Yoyleland to the Grasslands instead of the Plains.
- Fries regains all his fries, presumably from the Grotatoes or by dying and getting recovered.
- Bomby is recovered.
- Yellow Face stops being covered in Rocky's vomit.
- Coiny recovers from his burns from the boiling oil after doing "deep fried breaths" with Fries, although he may not have burned badly due to being made of metal.
- Woody recovers from his burns from Bomby's explosion.
- Needle cuts ties with FreeSmart, and becomes close friends with Coiny and Pin again.
- Nickel learns that the Wall Teleporter was the first thing Tennis Ball took from the Science Museum, as Golf Ball says he is aware of this in BFB 12, but wasn't around when Tennis Ball showed it to Coiny.
- Everyone who is trapped in the Locker of Losers is freed, most likely due to the Wall Teleporter. However, a faster way may be found, as BFB 1 takes place 14 months after IDFB 1, which is far less than the ~40 months the Wall Teleporter would take to free everyone.
- Black Hole regains his massive size and goes back to Space.
- Lightning gains arms and kills dozens of people.
- Cloudy starts a large collection of various things.
- The Locker of Losers leaves Yoyleland before Donut and Barf Bag are freed, as TPOT 4 is their first time there.
- Pin regains her red color, possibly with the help from Roboty's red tint.
- Grassy, Saw, and Nickel's assets get updated.
- Liy, Stapy, Foldy, and Loser join the main cast. Liy kills at least one person.
- In contrast, Evil Leafy leaves the main cast, and something may happen to her, as every Evil character recommended in BFB+ is a cardboard cutout, implying that they do not exist anymore.
- By the time they arrive, the TLC/LOL is either gone, left behind or destroyed, as Liy and Stapy have no idea what it is in TPOT 11.
- Yoyleberries may become increasingly rare outside of Yoyleland. Barf Bag calls them a collectors item worth gold in TPOT 4, and any depiction of Yoyle food outside of the biome is a cardboard cutout.
- The entrance to Golf Ball's Underground Factory gets relocated to the Grasslands, retaining the classic green grass from BFDIA.
- Gelatin moves his steakhouse to the Grasslands.
- Leafy stops being made of Yoyle Metal.
- Firey is set free from his cage.
- New personal recovery centers, such as those owned by Bubble and Pie, are built.
- The Hand-powered Recovery Center is either destroyed or stops being glued to the ground, as it does not exist anymore as of when Black Hole sucks up the rest of the recovery centers.
- Leafy is forgiven for stealing Dream Island, while most of the freed LOL characters are unaware of her actions.
- Firey is unaware of this before BFB 15.
- Donut acquires a syringe of the Twinkle of Contagion, which he won't have the opportunity to use until BFB 6.
- Tennis Ball and Remote play tetherball.
- Firey and Teardrop take Gelatin's Earth class.
- Firey partially gets over his fear of heights, as he was completely fine walking on his Team Tower's tightrope in BFB 18 and he only points out Woody's fear of heights in BFB 23.
- Coiny is unaware of this before BFB 11.
- Pencil stops seeing Match as "too needy".
- Book and Ice Cube stop having close connections with FreeSmart.
- Something traumatic happens to Book that makes her fear abandonment.
- The events of Paper Towel take place.
- The animation style changes from the late BFDIA-IDFB style, to the early BFB style. It could be implied that the Yoylite might be related to this change in the artstyle, as seen in the post-credits scene in BFDIA 17.
- Lollipop acquires Fork Repellent to sell.
- Four and X plan and set up Battle for BFB after Four makes A BFDI and plans to make another season.

- Several contestants' personalities begin to change.
- Pencil and Match become ruder.
- Flower becomes nicer.
- Pillow becomes more murderous, presumably due to further research.
- Pin likely becomes regretful of the ways she acted during BFDIA, especially since she claimed that it "sucked" despite it being her best season she has competed in.
- Yellow Face loses hatred towards the color purple, as he seems fine with having Marker on his team in BFB (while still retaining his hatred towards Purple Face, likely due to them being arch-enemies and overall opposites).
- The box where Purple Face is trapped in is taken to Yellow Face's warehouse.
- Golf Ball's Underground Factory and Gelatin's Steakhouse have the pink paint removed from them.
- The Eiffel Tower is rebuilt without the Clubhouse of Awesomeness, as it appears in BFDI Mini, which is canon.

- Pen somehow acquires fifteen trevigintillion nine hundred ninety-nine duovigintillion nine hundred ninety-nine unvigintillion eight hundred vigintillion dollars between BFDI 21 and BFB 1.
- Something happens to the revival Season 2 episodes, as Four and X do not acknowledge, or are somehow unaware of the high vote counts reached in BFDIA 7 and onwards, despite supposedly having the entirety of BFDIA archived in the A BFDI.
- Firey and Gelatin stop being best friends, as they seem to have drifted apart in later seasons, but remain on good terms in BFB 25.
- Firey becomes friends with Coiny, Needle, and Pin, as he calls them his pals in BFB 1.

- Gelatin learns about Firey and Leafy's history, as he was able to give a recap of it to Lollipop in BFB 22.
- Barbecue Sauce dies at some point before TPOT 9, as a corpse of them is seen.
- This may also just be a dead body from the past, and they are alive again.
- Black Hole sees the FreeSmart SuperVan, the swings, and the Beryllium Fortress, Destruction Impossible at some point before TPOT 10, as they appeared in his nightmare during that episode.
- Lewis may be recovered as he could have died in BFDIA 10 and is alive in TPOT 14.
- Tree and TV do not interact with each other, as TPOT 17 confirms they have not have any shared times together.
