you may think that Bikini Bottom is a suspicious place.

but beneath the murky depths of this strange underwater city

are even murkier depths.

This is Bikini Bottom Mysteries.

During the course of our investigations,

we've made countless shocking revelations.

But we believe we haven't even scratched the surface of this

ocean full of secrets.

Here we just a few of the suspicious fish lurking in Bikini Bottom.

[laughing manically]

Exhibit A: Flats.

We all know Flats the flounder, an expert square dancer.

We got square dancing!

With a talent for chest hair calligraphy.

But what does he have against SpongeBob?

I'm SpongeBob.

From the very moment they met...

I'm gonna kick your butt.

Flats made SpongeBob an enemy.

Can't you see he's gonna kick my butt?

There's something wrong with this picture.

What if we told you this isn't the first time these two met?

In fact, they knew each other well enough

the SpongeBob invited him to this Texas party.

Howdy y'all!

So why the facade?

I'm SpongeBob.

Who exactly are they trying to fool?

And could there be another reason for Flats' grudge against SpongeBob?

A reason from even deeper in their past?

That's right. Long before this supposed first meeting,

SpongeBob hid in Flats' bathroom,

and trapped him using a high-tech net launcher.

Was this they're true first meeting?

Maybe the day SpongeBob decided to go fishing

was the day Flats decided to hold a grudge.

But Flats is just the beginning.

Exhibit B: this mysterious little girl.

The daughter of Norma.

Get in the car, kids.

You've seen her around town always acting innocent and sweet.

Mommy, what is that thing?

As if she has nothing to hide.

But tell us then,

why does a child need to attend a driving class?

But what's even stranger,

in this class she actually looks older.

Does she somehow age faster than the sea creatures around her?

Is she a time traveler?

Could this be a version of her from the future?

Come back to warn her younger self about something?

This raises more questions than it answers.

Just like exhibit C: Dr. Manowar.

Who could forget poor Dr. Manowar?

The guy that got stung by Big Lenny and lived.

- Ow! - Touch.

But hold your sympathy,

because even Dr. Manowar seems to be hiding something.

Doesn't he look familiar?

Let's look back at one of our earlier investigations.

An investigation regarding the purple doctor fish.

The same face, the same voice,

and the same... glasses?

Are they the same fish?

You may have thought this case was already closed,

but take another look at Dr. Manowar.

Is it possible that Dr. Manowar is yet another disguise

of Dr. Gil Gillians?

Just how many doctors do you need to be, Gil?

- Flats... - I'm gonna kick your butt.

- A strange little girl... - Mommy, what is that thing?

And now a new lead in the case of the purple doctor fish?

Ow!

We may never know why Bikini Bottom holds so many shady fish,

but one thing's for sure.

There are plenty more where that came from.

And now, a Bikini Bottom Bonus Mystery.

Bikini Bottom has so many secrets

that even the rocks are hiding something.

It's a rock!

A rock!

If these are just ordinary rocks,

then how is SpongeBob able to drive this rock?

Especially when he doesn't have a license.

Or even a steering wheel.

And that's not all.

- Remember Rocky? - He's got nerves of steel!

The champion of the 102nd Running of the Snails.

Well, we've uncovered startling new evidence

that suggest that Rocky is not a snail.

Patrick, that's a rock.

No, he's not a snail at all.

How does a rock win a race?

Are the rocks in Bikini Bottom alive?

Rock buddy!

File this one under W for wait a minute.
