Note: All images are put in order.
The film Back to the Future apparently exists in the HTF universe.
Sniffles is one of the few people who prefer cookies and milk over popcorn.
Sniffles likes action movies.
Thank goodness for the rewind button.
Sniffles, look at what your doing.
Well, your distraction will go to give in this...
The cup seconds before breaking with the floor.
You will go to need take another cup now...
Not going to cry over spilled milk, are you?
Sniffles about to invent again.
Now how are you gonna mow your lawn?
At least he doesn't wear clothes anyway.
Of course, every invention needs a light bulb.
And cleaning up the milk and getting a new glass would have killed you how?
Sniffles puts time travel to the test.
Back to the past he goes.
Cookies and milk for a job well done... But only for a second.
"Sniffles! It's an emergency!"
Lumpy explains that Toothy broke his arm.
Sniffles needs a minute to take off his goggles.
Lumpy has no idea what to do.
A "blink and you'll miss it" moment (look to the top-right).
"Gnillaf m'I! Pleeeeeeh!"
Walking away from the slide.
Sniffles plans to prevent Toothy's injury from happening.
"Now to straighten out this slide."
Sniffles watches from the bushes.
The main quartet arrives to play.
Toothy gets on the slide.
This slide will never learn.
Sniffles knows he's screwed up. Good thing he has a time machine.
Sniffles' second plan to save Toothy.
I'm sure you'd need permission before dismantling a public slide.
"Where did the slide go?"
"Come along and play with me."
Shocked Giggles and Toothy.
"Oh my Kenn!" Also, wasn't that slide destroyed?
Oiling up the rusty old seesaw.
Lumpy coming to join Cuddles on the seesaw.
I've heard of flying squirrels, but flying bunnies?
Cuddles flying through the atmosphere (How strong and/or fat is Lumpy)?
Cuddles will go down in history as the first rabbit to visit space.
It takes precise aim to do this.
This explains how the plane got there, and how Sniffles became a pilot
. But one question remains: Where did he get this thing?
Why swings shouldn't be built near airports.
Banana peels shouldn't go there.
Looks like it's garbage day.
When you mix compost with garbage, little animals will suffer.
"Damn! This is starting to get annoying."
Looks like anteaters and ants were friends once. I wonder what anteaters were called then. Probably ant-friends.
Oh. I guess that's how they became extinct.
Sniffles judges the distance Giggles will fly...
...and where to plant the trees...
...then plants acorns for the future.
Cherish this moment, Sniffles. Because this is the only time you'll eat an ant and get away with it.
As Sniffles leaves the past, he leaves his mark on the ground.
"Yes I did, now let me try."
The seeds grow as time flies by.
Trees save lives, but we can't say the same about swings.
You could have just went back in time to stop yourself from planting those trees.
Sniffles demolishes the entire playground.
"Where did the playground go?"
"This means we can't play..."
Any die-hard HTF fan knows where this is going.
Well we all know where this is going.
Lumpy agrees to go faster.
Toothy is having the time of his life.
Toothy before letting go.
This time Toothy hits a tree facing the left.
Giggles hugs the pole with all her might.
The pole wants to make sure she stays dead.
Cuddles hanging on for dear life.
Lumpy must have Splendid levels of strength if he can break off Cuddles' arms like this.
Cuddles seconds before death.
Why did Sniffles leave this thing here? Death: Cuddles
"Better go get Sniffles again."
Sniffles is tired after a long day of time traveling.
Whatever you do, don't approach the milk and cookies.
Sniffles realizes the consequences of time travel.
See what happens when you cry over spilled milk?
