My cama would make it self
New books on every shelf
And then I'd cast a spell, Abracadrabra
My pets would talk to me
And then we'd all have tea
Create a pair of shoes
That would know all the moves
I'd always find the groove, feel the beat now
And with the spotlight on
I'd twirl perfectly

If I had magic
Magic, magic
If I had magic
Magic, magic

I'd make a chocolate lake
Turn cabbage into cake
I'd text without mistakes, lol Yeah
I'd dream a pair of wings
And I would fly away
I'd zoom across the sky
Make it snow in July
I wouldn't be so shy, "pleased to meet you"
I'd do just what I want
Like every single day
Hey-hey-ey

If I had magic
Magic, magic
If I had magic
Magic, magic

And I could do anything
Suddenly I would be
Everything that I dreamed I could be

If I had magic
Magic, magic
If I had magic
Magic, magic
If I had magic
Magic, magic
Magic, magic
If I had magic

"Hailey (Barbie) and her friend Kristen are two ballet students at a special dance school. Their ballet instructor is always telling Hailey to keep to the routine and to stop changing the dance. But, Hailey loves to make the dance her own. One day, Hailey's dance shoe rips, so she and Kristen go downstairs to the seamstress/cobbler to get her shoes fixed. Madame Katarina gives her a pair of magic dance shoes, which transport the girls to a magical place where Hailey becomes the lead dancer in all the classic ballets. And true to form, she keeps changing the dance routines a bit. One of the girls is kidnapped por the evil Snow Queen. But with the help of her friend, and por staying true to herself, she dances her way to a bright future."

Note that apparently whoever wrote this sypnosis got Hailey and Kristyn mixed up and also misspelled Kristyn's name, so just ignore that.
