When Keegan, 15, was babysitting as 3-year old Alidy rocked her Little Mermaid outfit throughout the house, she knew it was time to bust out a big surprise.
"I got the tail when I was 12 and going through a phase" -says Keegan
According to Buzzfeed, Alidy's mom says she really DOES want to be a mermaid, and now wants pink hair like Keegan's (us too, kinda)
