Colourful animated numbers with googly eyes jump around and form the name "Wacky Number Songs."

A song says IT'S THE WACKY WACKY
NUMBER SONGS.
OH YEAH.

Ava stands in a nice bedroom filled with furniture. She is around 12, with two long braids. She wears a striped yellow shirt under a denim overall.

Ava says I WANT TO HAVE A PARTY BUT FOUR
CUPCAKES DOESN'T SEEM LIKE
ENOUGH.

She shows a plate with four cupcakes.

A Voice says ZERO THE HERO, AT YOUR
SERVICE!

Ava says HUH?
HOW CAN ZERO HELP?
DOESN'T ZERO MEAN, WELL,
NOTHING?

The cupcakes multiply.

Ava says OH!
I GET IT!
ZERO DOESN'T JUST MEAN NOTHING!
IF YOU PUT A ZERO AT THE END OF
A NUMBER, IT MAKES THAT NUMBER
TIMES TEN.
I HAD 4 CUPCAKES, BUT NOW I HAVE
4-0, AND THAT'S 40!

Against an animated background, she sings I'M ZERO, I'M A HERO!
THINK I'M NOTHING?
OH, MY DEAR, NO!
WHEN YOU HAVE 2 CATS BUT YOU
WANT 20, PUT A ZERO AFTER 2.
NOW YOU HAVE PLENTY!
MY NAME'S ZERO.
I'M A HERO WHEN
YOU MULTIPLY BY TEN.
WHEN YOU PUT ME AT THE END,
NOW THE NUMBER IS TIMES TEN!
I CAN DO IT WITH BIG NUMBERS
TOO!
IF YOU HAVE TEN ELEPHANTS AT
THE ZOO AND PUT ZERO AFTER
NUMBER 10, YOU HAVE A HUNDRED
ELEPHANTS IN THAT PEN!
MY NAME'S ZERO.
I'M A HERO WHEN
YOU MULTIPLY BY TEN.
WHEN YOU PUT ME AT THE END,
NOW THE NUMBER IS TIMES TEN!
NOW, WHAT IF ELEPHANTS ARE MY
THING?
I'LL PUT ANOTHER ZERO ON THE
END.
CA-CHING!
NOW A THOUSAND ELEPHANTS ARE
IN THE RING!
ZERO'S THE REASON THAT I
SING.
MY NAME'S ZERO.
I'M A HERO WHEN YOU MULTIPLY
BY TEN.
WHEN YOU PUT ME AT THE END,
NOW THE NUMBER IS TIMES TEN!

The Voice says UM, YOU'RE GONNA NEED A BIGGER
ZOO.
(elephant trumpets)

The song ends.

Ava sighs and says KEEP ADDING ZEROS TO MAKE IT A
HUNDRED, A THOUSAND, AND EVEN UP
TO MILLIONS AND BILLIONS.
A LITTLE ZERO CAN DO A LOT!
THAT'S A LOT OF CUPCAKES!
SEE YOU NEXT TIME!
