But are you sure you caught everything?

Here are 8 hidden SpongeBob Easter eggs you may have missed.

Number 8: volcano sauce.

[screaming]

By the powers of naughtiness,

I command this particular drop of hot sauce

to be really, really hot.

Sandy, wait!

Victory is yours.

Does the talking drop of hot sauce sound familiar?

If so, that's because it's the face and voice of none other than...

Tom Kenny, the voice of SpongeBob himself.

Number 7: Mrs. Puff's pictures.

Surprise!

To the greatest teacher ever!

Mrs. Puff's house looks pretty normal at first glance.

But take a second look at her interior decorating.

Here as she walks into her home,

on the wall behind her is a framed picture of her

walking into her home.

And in that picture, there's an identical picture.

And in that picture, there's another one. When does it end?

Number 6: to the dump.

It looks like the excitement of my artistic triumph

is too much for Squidward.

Oh well, back to the dump!

♪ To the dump, to the dump To the dump, dump, dump ♪

Now this one's harder to find.

But if you recognized SpongeBob's "To The Dump" song,

then you must be a 90's kid.

Because this song was also sun by Heffer the cow

in the hit 90's show Rocko's Modern Life.

Hef, let's get this garbage to the city dump.

♪ To the dump, to the dump To the dump, dump, dump ♪

♪ To the dump, to the dump, dump, dump ♪

And if that's not enough for you,

well, did you also know that Heffer and SpongeBob

are both voiced by Tom Kenny?

♪ To the dump, to the dump To the dump, dump, dump ♪

♪ To the dump, to the dump To the dump, dump, dump ♪

♪ To the dump, to the dump, dump, dump ♪

Oh boy, that was great.

Number 5: Uncle Sherm.

Hurry Gary, the scary robot movie is on.

Meow.

What do you mean I shouldn't watch this?

Scary movies don't always freak me out.

[whimpering]

What if Mom is a robot?

What if Uncle Sherm is a robot?

So Uncle Sherm probably isn't a robot,

but who is Sherm anyway?

Well, one of the directors of SpongeBob is actually named Sherm Cohen,

and he's also the storyboard supervisor for this episode.

Coincidence? We don't think so.

Number 4: Opposite Day.

[speaking gibberish]

[laughing]

Speaking gibberish seems like a normal thing to do on Opposite Day.

Right? But this is more than just gibberish.

If you play this clip backwards, you can hear a hilarious joke.

- Hey, Patrick. - I give up.

To get to the opposite side!

[laughing]

OK, maybe it's not hilarious, but it's still cool.

Number 3: Patchy was here.

Nematodes are people too.

Ha! Those nematodes.

Here's one somebody didn't finish.

Squidward smells...

Good.

Now let's forget about how Squidward smells for a second,

and take a look at what else is written on the dumpster.

"Patchy was here."

Patchy is the name of the human pirate who heads up the SpongeBob fan club.

Played by Tom Kenny.

How did he get to the bottom of the sea?

Number 2: Dennis in the sand.

[yelling]

And... stop!

Can you spot the Easter egg?

This sand man, or sand fish I guess, is a perfect replica of Dennis,

the hitman from the SpongeBob movie.

Number one: the living room.

You've always been the only one for me.

OK, this one is a lot of Easter eggs in one, so brace yourself.

This board game is the Flying Dutchman's Treasure Hunt

from the episode Arr.

Based on a real treasure map!

And this board game is Eels and Escalators,

from the episode Sailor Mouth.

Escalators, escalators, escalators!

Eels?

Right next to that is the Mermaid Man toy

that comes with every Krusty kid's meal.

The new Krusty kid's meal!

And for a limited time, get your free toy inside!

And in the corner is a Krusty Krab pizza box.

♪ Krusty Krab pizza ♪

♪ Is the pizza, yeah for you and ♪

♪ Me! ♪

Up top is a box of Kelpo cereal from the episode Waiting.

What's this?

On the floor is a spilled pint of rocky road ice cream,

made with real rocks.

Rocky road!

With real rocks!

And if you look around, you can find the letters F, U and N.

A reference to the letters SpongeBob uses when he sings the Fun song.

♪ F is for friends Who do stuff together ♪

♪ U is for you and me ♪

♪ N is for anywhere And any time at all ♪

♪ Down here in the deep blue sea ♪

That's it for today.

Remember to keep your eye out for more SpongeBob Easter eggs.
