Back at Atlantica, the merchildren enter the throne room and gossip about their younger brother's behavior.

"I'm talking about Josh, that's who!" Ashley cried.

"What about him?" Abby asked.

"He sure is acting fishy lately!"

"I'll say!" Jordan added. "Swimmin in circles! Chasing his tail!"

"That boy is up to his gills or something!"

(Ashley)
He's dizzy and he's dreamy

(Jordan)
His head's up in the foam

(Abby)
His eyes have gone all gleamy
It's like no one's home

(All)
He floats away the days
Mopin on the coastal shelf

(Jordan)
Is he ill?

(Abby)
Or insane?

(Ashley)
Is it water on the brain?

(All)
What has got him bothered so?

(Abby)
It's the bends!

(Jordan)
It's the flu!

(Ashley)
Gosh, I wish we had a clue!

(All)
Oh wait!
Oh dear!
Good grief!
It's clear!

He's in love!
He's in love!

Pounding heart!
Ringing bells!

(Ashley)
Look, I think he's even wearing brand new shells!

(All)
He's in love!
He's in love!

Glory be!
Lord above!
Gotta be he's in love!

Brendon swims in, looking for Josh.

"Hey Brendon!" Ashley cried. "You notice anything weird about you-know-who?"

"You mean Josh? I'll say!"

(Brendon)
He acts like he don't see me
He doesn't even speak
He treats me like a sashimi left over from last week

You see him late at night
Tossing in his ocean bed

(Merchildren)
Shoop shoop

(Brendon)
And he sighs and she swoons
And he's hummin little tunes

(Merchildren)
Even has a sort of glow

(Brendon)
What on earth could it be?
Hammer head can see!

(Jordan)
That sigh!

(Abby)
That glow!

(Ashley)
That swoon!

(All)
Oh no!

(Brendon)
He's in love!

(Merchildren)
He's flipped it never fails!

(Brendon)
He's in love!

(Merchildren)
All hot beneath his scales!

(Brendon)
See his hops
How they swish

(Merchildren)
Well a well a well don't you wonder who's the lucky seafood dish?

(Brendon)
He's in love!

(Merchildren)
He's found a deep sea hunk!

(Brendon)
He's in love!

(Merchildren)
And now he's as good as sunk!

(Brendon)
Save his blush!
See his grin!
Gotta be love!

(Merchildren)
Gotta be love he's in!

(Brendon)
Josh and someone
Swimmin in the sea
K I S S I N G!

(Jordan)
He's in love!

(Abby and Ashley)
He's in love!

(All)
He's in love!

He's in love!
He's in love!

(Brendon)
Plain to see!

(Merchildren)
Plain to see!

(Brendon)
No mistake!

(Merchildren)
No mistake!

(Brendon)
Look at those moon beams in her wake!

(Merchildren)
Look at those moon beams!

(All)
Obvious what they must be
Symptoms of

He's in love!
He's in love!
He's in love!

Yeah! Yeah!

King Bill Dun and Ryan enter, just in time to hear Brendon bring the song home.

"In love? My little Josh? So that explains it!"

Brendon tries to swim away inconspicuously.

"Just a minute there Brendon."

"Who me?"

"You know Josh as well as anybody. Who's the lucky merman?" King Bill Dun asked.

"Gee, I don't know." Brendon replied. "I didn't know it was love until the second chorus!"

"Ryan? Any ideas?"

"I've tried to stop him sire, but he doesn't listen! I tell him, Josh, you've got to stay away from those humans, they're nothing but trouble!"

Brendon bolts.

"Humans? What about humans?" King Bill Dun asked.

"Who said anything about humans?"

Ryan scampers off. King Bill Dun pursuits him.

"Ryan, have you been keeping secrets from me? Where is that boy?!"
