What does the Elf say?

Today Cassie had a Christmas concert at College Street School Her class sang "What does the Elf say?" They didn't change much in the song. This is the song as far as I know.

Dog goes woof
Cat goes meow
Bird goes tweet
and mouse goes squeak

Cow goes moo
Frog goes croak
and the elephant goes toot

Ducks say quack
and fish go blub
and the seal goes ow ow ow ow ow

But theres one sound
That no one knows
What does the elf say?

Ring-ding-ding-ding-dingeringeding!
Gering-ding-ding-ding-dingeringeding!
Gering-ding-ding-ding-dingeringeding!
What the fox say?

Wa-pa-pa-pa-pa-pa-pow!
Wa-pa-pa-pa-pa-pa-pow!
Wa-pa-pa-pa-pa-pa-pow!

Hatee-hatee-hatee-ho!
Hatee-hatee-hatee-ho!

What the elf say?

Joff-tchoff-tchoffo-tchoffo-tchoff!
Tchoff-tchoff-tchoffo-tchoffo-tchoff!
Joff-tchoff-tchoffo-tchoffo-tchoff!
What the elf say?

Big blue eyes
Pointy ears
Making toys
and spreading joy

Tiny feet
in the snow
Suddenly you're ready to go

Your coat is red
So beautiful
Like an snowflake in disguise

But if you meet
a friendly reindeer
Will you communicate by
mo-o-o-o-orse?
mo-o-o-o-orse?
mo-o-o-o-orse?

How will you speak to that
ho-o-o-o-orse?
ho-o-o-o-orse?
ho-o-o-o-orse?

A-hee-ahee ha-hee!
A-hee-ahee ha-hee!
What does the elf say?

A-oo-oo-oo-ooo!
Woo-oo-oo-ooo!
What does the elf say?

The secret of the elf
Ancient mystery
Somewhere deep in the snow
I know you're hiding
What is your sound?

Will we ever know?
Will always be a mystery
What do you say?
