There's a two-year-old girl in Florida named Harper Comparin who was born with severe spina bifida. So her parents didn't know if she'd ever be able to walk.
But now she is . . . and the song "Baby Shark" played a big part in it.
A doctor named Michelle Schultz has been working with her at Johns Hopkins All Children's Hospital in St. Petersburg.
And she wanted to get her up and moving. So she decided to see if "Baby Shark" would help.
Whenever it comes on, Harper gets all excited. And they use it kind of like a metronome, where she has to walk to the beat.
She could only take a few steps at first. And her parents say even that was amazing.
But now she's tooling all over the place, and getting stronger every day.
