"Last BFDI" is a video created as a celebration for 20,000 subscribers. It shows a vertically scrolling animation of a Rube Goldberg machine containing all 31 contestants of BFDI and BFDIA combined (but no hosts), creating and destroying them over and over. The song in the video is based on "Last Step" by Dubmood who was a member of Razor1911.

|Blocky||Pin's point is removed, resulting in Blocky||Blocky is cut into three pieces; one for Match, one for Fries's container and one turns into Eraser|
|Bomby||Results in Match's ashes covering up Tennis Ball||Ignited with firebox, then explodes, resulting in Rocky|
|Book||The paper that Pen writes on is closed into a book, which Pen's cap covers in blue and green||Dora hops out of Book's illustration and eats her|
|Bubble*||Excess water from Teardrop falls onto a platform, which is blown by a blow-dryer, creating Bubble||David's crushed body is splattered onto her, giving her dimples and turning her into Golf Ball|
|Coiny||Fries' fries fall on Nickel turning him into Coiny||Coiny notices Nickel and falls down a funnel to create Needle|
|David||Dora's hair falls off turning her into David||His head is cut off and turns into Snowball, while his crushed body covers Bubble in dimples|
|Donut||A hole is punched in Yellow Face||Falls down cutter to make Fries' fries|
|Dora*||Book opens and Dora comes out of her article illustration||Dora's hair falls off turning her into David|
|Eraser||Comes from taking part of Blocky and pushing the top part back||Collides with a piece of wood from Woody to make Pencil|
|Firey||Match is burned by a lighter to make Firey.||Bubble-blower makes water flow down to extinguish him|
|Flower||She's the first plant to come out of the flower pot when it's watered||She has her body cut off by a knife, her petals fall off, turning Gelatin into Puffball, and the middle of her face turns into Yellow Face|
|Fries||Fries come from Donut; container comes from one of Blocky's parts||
Fries turn Nickel into Coiny; container is crushed into nothing
Note: Fries and container are separate in both the commencement and the termination. They're temporarily put together in between.
|Gelatin*||The second plant to come out of the flower pot when it's watered is a green bush, which collides with Dora's hair to make Gelatin||Flower's petals turn Gelatin into Puffball|
|Golf Ball*||Results from dimples being splashed on Bubble||
She, Leafy and Puffball are zapped, fusing into Tennis Ball
|Ice Cube||Teardrop is pulled into a freezer and comes out as Ice Cube||Ice Cube walks on a heating element and melts, watering the flower pot|
|Leafy*||The second plant to come out of the flower pot when it's watered is a green bush. One of its leaves is cut off making Leafy||She, Golf Ball and Puffball are zapped, fusing into Tennis Ball|
|Match||Results from part of Blocky on top of Woody being crushed thinner||Is set on fire by a lighter to create Firey|
|Needle||Results when Coiny falls down the funnel||Needle is turned upside down and stuck into Ruby to make Pin|
|Nickel*||Rocky's remains are compressed against the platform above him, resulting in Nickel||Fries' fries turn him into Coiny|
|Pen||A cap generator makes a cap, which falls on Pencil to make Pen||He disappears when Book is being closed|
|Pencil||Eraser and a piece of wood from Woody collide to make Pencil||A blue cap falls on her to make Pen|

|Puffball||Collision of Gelatin and Flower's petals||She, Golf Ball and Leafy are zapped, fusing into Tennis Ball|
|Rocky||Emerges from Bomby's explosion||Is mined with a pickaxe to reveal Ruby, and his remains are compressed to create Nickel|

|Spongy*||None, just sits there doing nothing||None, just sits there doing nothing|
|Teardrop||Snowball is melted to create her and Bubble||Pulled into freezer to make Ice Cube|
|Tennis Ball||Golf Ball, Leafy and Puffball are zapped, fusing to make Tennis Ball (Get it? Golf Ball is a sphere, Puffball is fuzzy, Leafy is green, and Tennis Ball has all three of these properties!)||Match's ashes cover Tennis Ball up, making Bomby|
|Woody||The second plant to come out of the flower pot when it's watered is a green bush. One of its branches is cut off to make Woody||A piece falls off of Woody, making Pencil, and the rest of Woody forms Match|
|Yellow Face||Results from Flower's face without the petals||Hole punched in him to make Donut|
