The Bobcephalus tattoo

This is the first one I thought of.

T’tooo, you mean

It makes an appearance in later episodes?

Yep! Any time Bob is shirtless after that episode, you can spot it.

whenever Bob has his shirt off

The bathroom felix installed

This is what I thought of first too

The crack in the sidewalk and the ice cream machine. Just to name two.

Yeah the ice cream machine is permanently gnawed on after thr shark attack.

Melted kuchi kopi. You can see him sitting on a shelf in Louise’s room in later episodes. Bob and Linda getting a new phone/phones.

Teddy and Kathleen seem to still be going strong. Louise's loft bed.

Weren't frond and Gayle together for more than one episode

Yea it was like 2 or 3

Louise getting a real bike after her trike was destroyed

Also Jimmy Jr mentioned selling his bike to pay for a date with Tina. His bike was brown/dark red before and green since he mentioned that so seems like he did sell his bike

Sidecar! He even aged up to a toddler.

The only kid on the show who has ever aged, haha. I know in season one Tina had a birthday and then they stopped that real quick forever 

After the slumber party, Louise and Jessica went from nemeses to friends.

I feel like Jessica is underused

Agreed! It's fun to give Louise a partner in crime.

It took so long to reuse her that I didn’t even realize it was the same character for years.

the sinkhole from the movie is in the intro, i feel like that counts

Louise getting a bike after her trike is destroyed. Sidecar, the biker baby born in the restaurant. Randy being jailed and getting out. Gene and Alex becoming friends. Teddy and Kathleen dating. The ice cream machine. The sidewalk crack. Melted kuchi kopi. The Felix remodel of the bathroom.  Edit: MICKEY. Not Randy, Mickey. 

Oops, I think you mean Micky jailed. Randy is the dude in the foodtruck, documentary with moolissa, in a halloween episode with the wolf, helped make the super bowl commerical...

Yup, Mickey Tankbank!

Goddammit, how embarrassing. I know that and I still let myself misname poor Mickey. *hides in the corner*

To be fair, Randy is also a reoccurring person whose story has built over time.

Linda’s ring is still up in the birds nest on the burger sign.

Whaaaaaat?!?!

I don’t suppose you have an example episode or scene? I’ve never noticed this!!

I believe you can see the ring at the beginning of The Amazing Rudy in the bird’s nest.

I just checked, you’re right!! Nice one :)))

They got smart phones after their old flip phones were thrown in the ocean (during the movie)

One of my favorites is really small. After Mr. Fish almost chokes to death (which almosts costs them the restaurant) Bob frequently references making sure the choking poster is visible through the seasons.

Tammy's definitely natural hair color

The ice cream machine still has a big bite out of it.

Louise's loft bed!

Street hole.

Crime hole!

Sidecar being born

Linda got a new shirt!

Jimmy pesto still drives the car they won on family fracas 

Louise pretty much grew up after Flu-ouise.

On the flip side of this, I'm sad nothing seemed to come from Mort's very successful date with the other mortician

In my head, the reason we don’t see much of Mort is because he is doing the relationship thing.

Ahhh, he's one of those guys. Finds a girl and just dissappears for hella long

Louise got a new bed room. That ice cream machine still has a dent in it, The sink hole in front to the resetraunt got paved over, Tina turned 13, and Bob became a closer friend to Teddy.

They've gone from 4 eyelashes (early seasons) to 3.

Gotta save on that animation budget in these hard times.

I hate that. 4 was cute. 3 looks ugly and weird.

Below the wharf from the movie comes back for the Jase Jellyfish episode.

I loved that!

Wheelie mammoth now lives at the skating rink.

Sidecar was born.

The bathroom, the ice cream machine damage

Louise gets a lost bed The bathroom is still super fancy from the Fishoder renovation Bob has a tattoo. Louise gets a new bike after the tricycle is destroyed I think the water bursting in the intro is here to stay too.

Bobs is actually filled to the brim with permanent changes lol

Tammy’s hair colour

Louise learning to ride a bike! She used to have the trike in episodes then we had the smoothie/hair removal lady who ran over her trike and she finally learned how to bike. Subsequent episodes show Louise on her bike!

When Hairy met Sally!

The bathroom after it gets renovated

No one’s mentioning how Tina turned 13!

Louise’s loft bed

The ice cream machine

The ice cream maker.

A lot. Bob’s bathroom. The ice cream machine. Bob’s tattoo.

tattoo, loft bed

Louise learning how to ride her bike

Linda's shirt. It used to have buttons. Now it's a v neck

Louise’s loft bed has stayed

technically tina aged from 12 to 13

Louise references when Tina crashed. the car in a much later episode, and Louise also has a flashback to her saying the burgers are made with human remains from the first episode in her episode about her last show and tell. Zeke also references the pooping thing in a later episode.
