and I think I now know what to call it.

[all gasp] "A Song for Ripple."

- Oh!

- Would you all like to hear it?

- Yes!

- Well, yeah!

- Yes, yes, yes, yes, yes, yes, yes.

- Okay, okay, but listen.

I'm all filled up with krill, so if you all want to travel with me, I sing it for you, okay?

I know you'll love it, but it's fine, you know?

It's no big deal.

- Okay, okay, okay.

- Yeah.

- Wow.

All right, well, we're about to head back down south ourselves, but how will we keep up with a giant humpback whale like you to hear the song?

- Oh, yeah, don't you worry your tiny little fins off.

I may be huge, but I'm a much better singer than I am a swimmer.

You'll be fine.

No big deal.

- Don't forget, Ludwig's songs can be heard for up to 20 miles from where he's singing.

- Yeah, so if you fall a little behind, it's A-okay.

All right, here is Ludwig's latest song in a personal concert just for you.

[laughs] But hey, it's fine.

It's no big deal.

[laughter] [Ludwig singing] - Wow.

- The song!

- It's beautiful.

- Whoa.

- I love it.

[singing continues] ♪ ♪ [laughter] ♪ ♪ - Bye, kids.

And before I go, here is the big finish.

[singing flourishes] - Wow!

- Wow!

Bye, Ludwig!

- That is so loud!

- See you next time!

- Bye-bye.

- Bye, Ludwig.

- Whoo!
