Need Help finding clip

I am looking for a clip but I do not know which season or episode it was from. Where they invited multiple studios who they lost against to create a dance competition. And some parents signed a waiver to allow their child to be filmed. The one I am specifically looking for is a clip of two young girls one blond and one brown hair both with long hair. It is a performance of a duet. If I am not mistaken the outfits were one blue and the other white. Or it could have been a black and purple one with a little hat. Please help me look for it. My cousin never gave me the episode so I could video record my performance.
