Original subtitles

Okay, now open your eyes.

Witness the masterpiece of morning.

[all inhale, exhale]

[whistles]

Now scream your gratitude at the sun.

I'm thankful for fruit!

-Secrets! -Skin!

My vast knowledge of prehistoric marine reptiles.

Now ball up that gratitude and cram it into your heart.

-Hmph! -[grunts]

-[grunts] -[thuds]

[gasps] Ichthyosaur!

Ichthyosaur?

Chip, I keep telling you, "They are extinct."

You don't know. You didn't see them die.

Wait, I know what that is.

That is a... a... a dolphin!

[dolphin squeals]

[all gasp, exclaim]

[squeaks] Merian.

-[all gasp] -[thuds]

Did that thing just talk?

[sighs exasperatedly] What are you doing here, Tara?

You know this dolphin?

Yeah. She's my... sister.

What? Ow.

-Ugh, I'll explain. -[squeals]

So, our parents are marine biologists.

They practically invented

the field of dolpholinguistics.

They raised me and Tara together in a tank to see

if a dolphin could learn to use human speech.

[audience applauding]

A... B... Hmm...

-Psst. -[squeaks inquisitively]

[Merian in Dolphish]

C...

[Merian] Tara made headlines

for learning to squeak the alphabet.

Meanwhile, I received no recognition

for learning fluent Dolphish.

Wait. You're Tara from Tara and the Human Sibling?

You were huge on the dolphin forums back in the day!

[squeaks bashfully]

Yup! That's her. So, what are you doing here, anyway?

[in Dolphish] Just was checking on you.

Uh... [scoffs] Don't worry about me.

I'm thriving here.

You can go home and tell Mom and Dad

the human sibling is just fine.

[in Dolphish] Oh, I just got here!

Oh, yeah, I'd love for you to stay,

but we already have a whole agenda set for today,

and it's all land-based activities, so...

-[all] Aww. -Wait!

[panting] I made this once,

in case a dolphin ever wanted to leave the water and be my friend.

Cool. Cool, cool, cool. That's great. Thank you, Pliny.

I guess we're spending the whole day together now,

-so that's pretty-- -[all] Yay!

-[Tara squeals] -[kids cheering]

-[Merian grunts] -[Tara squeaks]

Only you can do that, Tara!

[Merian] Sun beams require a delicate touch.

Hey!

-[all exclaim] -Wow!

She's breaking all the rules.

-[kids cheering] -Tara, you're the best!

Tara!

[in English] Three, two, one...

[sonar pulse blasts]

[Larry grunts, chuckles] Oh, I can feel it in my skull! Oh!

Tara, you can't use echolocation!

If you're just gonna cheat, we are skipping all the way to "Help Dr. Lullah."

But, Merian, what about balloon animal hour?

[grunts] Yay!

Oh! Yay!

All right. Last thing on the list. We have to clean the peanut butter

out of Mr. Okay's pan pipes.

I can't believe you haven't learned how to play 'em yet.

Once I learn how to play, she'll stop putting peanut butter in there.

It requires a little dexterity and a lot of fingers.

[♪ plays pan pipe notes]

So you probably have to sit this one out, sis.

Quiet! I'm close to discovering the compound for Instant Tree.

-[beeps] -[liquid glugs]

-[beeps] -Argh!

Hmm. [squeaks]

[all gasp]

[gasps dramatically]

I am so sorry, Dr. Lullah. I'll get my sister out of here.

The lab is just no place for a dolphin.

-[exclaims] -[glass shatters]

-[all gasp] -Wow!

You've done it! Who's the lone genius out of the dud bunch?

-Tara! -It was Tara!

-Tara! -She's the genius!

-Well done. -[squeaks]

You have trophies?

[clicks tongue] That was my last one.

[kids cheering indistinctly]

-[Merian] Okay, time for bed. -[squeaks sadly]

It was so good to see you, but you have to go back to the ocean now.

-So, bye. See you later. -Wait!

We could have a sleepover!

[squeaks happily]

Well, I'd love to,

but we can't have guests,

-uh, right, Dr. Lullah? -I don't care what you do,

so long as you de-cheese the shakuhachis.

-[blows] -[splatters]

[Chip gagging]

Wait, Chip, I thought you said truth.

This is my truth.

Ooh, Merian's turn!

Truth or dare?

What he said. Truth. I don't care.

Okay! What was the best part

about growing up with a dolphin for a sister?

I don't know.

[gritted teeth] So hard to choose.

Ooh-hoo-hoo, I bet!

-[squeaks] E... Z... -[blows]

Esteemed colleagues...

-[kids gasp, exclaim] -Oh, no!

The Cetacean Research Institute

is proud to share the latest findings

in human-dolphin communication...

-The Sister Swim! -[audience cheering]

[squeaks]

[gasps] I've only read about this!

[Mom] Looks like they're starting off with a reverse mermaid--

Changed my mind! I choose dare!

Okay.

I dare you to do the Sister Swim with Tara right now!

-[Tara squeaks] -[all cheer]

-I wanna see you do it. -Uh, no way.

[squeaks encouragingly]

Tara, we're not calves anymore.

You said "dare."

Okay! Who cares?

Let's do it... [fake laugh] the Sister Swim!

-[squeals] -[all cheering]

-[all cheering indistinctly] -Let's do it!

Yes, fantastic!

I can't believe we're about to see this in person!

[shivers]

-[squeaks] -Gah! Quit it!

All right. All right, fine. We'll start.

[forcefully] Ta-da.

[gasps]

Aah! Whoa! [thuds]

[screeches]

[Merian screams]

Oy, yeesh.

Okay, let's just skip to the finale.

[whispers in awe] The sister spin!

-[thuds] -[screams]

Ooh, yikes.

[in Dolphish] You're not even trying!

"Not trying"? Not trying?

All I've ever done is try!

Try to stomach the wet birthdays

and the endless tuna dinners! Try to live up to you!

[in Dolphish] That's not fair!

I'll tell you what's not fair.

I finally have a summer all to myself,

and you had to show up and outshine me.

[both arguing in Dolphish]

Just go home! I'll be back in a few months.

[in Dolphish] But the Sister Swim...

No! I am done doing the Sister Swim!

[in English, tearing up] Oh, why? [whimpers]

Because you're not my real sister!

[all gasp]

Oh! [whimpers]

[continues whimpering]

Okay, back to the game, Larry.

I dare you to fill your bathing suit with sand.

Yes, ma'am.

Grr!

-[Merian's mom] And that was the Sister Swim! -[cheering]

Tara once again wows the audience with her intelligence.

Oh... [chuckles] and... and the human sibling was there as well.

[scoffs] Dumb.

-Nom, nom. -[Mom] Don't fill up on fish.

We still have birthday cake.

-Yay! -[squeaks] Yay!

[Tara squeals and Merian cheers]

So I'll marry Johnny,

-and you marry Zack. -[Mom giggles]

-Mom, are you filming? -[in English] Mom, stop it!

[chuckles]

-Tara, stop! -I can't!

[laughs, snorts] Oh, my gosh, we got so hurt.

[Mom] Look, honey, Tara's about to say her first words!

[in English] M... M... Merian.

[sighs]

Oh, no.

What have I done?

More sand, more sand, Larry. Put more sand in your pants.

Tara!

I'm so sorry. I didn't mean what I said--

-Whoa! -[snarls]

-[screams] -It's an ichthyosaur!

Am I right? Pliny, is that what I'm looking at?

That animal? Right there?

The one that you said was extinct?

[grumbling] Yeah, yeah, yeah. It's an ichthyosaur.

-[roars] -[squeaks] Hi-yah!

[squeals]

Tara! You saved me.

[in English] Aw, I'm sorry!

Shh, I'm the one that's sorry.

I didn't mean those things I said.

I don't deserve a sister like you.

[croons in Dolphish]

Aw, I... [croons in Dolphish] [in English] you, too!

[roars]

Oh, no, Merian!

Wow, Pliny, is that-- Are you seeing this?

-Yeah, yeah, there's two-- -Ichthyosaur-"s." Two of 'em.

[roars]

[squeaks]

We're so rusty, do you think it will work?

[in English] Yeah!

We gotta go help them!

-[grunts, thuds] -Wait!

[gasps] It's happening!

[squeaks]

[Mom] They're starting off strong with the faithful footsteps.

Right into some figure eights.

[squeaks]

[squeaks]

[Mom] I don't believe it. They're doing the Sister Spin!

Hmm, I should call my sister.

[squeaks]

[roars]

[sonar pulse blasts]

Aw, dang, wow! That's the last two ichthyosaurs, huh?

What's that word? What do you call that, Chip? Um, what do you call that

when the last two of them are gone

and there's no more of those things?

Extinct. Yeah, extinct.

[all kids cheering] Yeah, you did it!

-[Sara] Dang! -Merian, you're amazing!

-[squeaks sadly] -[Merian] Wait, Tara!

-[squeaks] -It's your turn for truth or dare

and I dare you to stay one more day.

[happy squeaks]

And I dare Larry to put more sand down his pants.

Yes, ma'am.
