Lyrics generator (under 300 characters) mines over 600

JavaScript

I tried cancelling the white spaces and i was still left with slightly over 300. so i just beautified the code for you guys. But seriously though, what is the “legitimate way” of actually hitting under 300 without backspacing all the white spaces
my code :

function babySharkLyrics() {
    let arr = ["Baby", "Mommy", "Daddy", "Grandma", "Grandpa"]
    let str = "";
    let j = 0;
    let n = 0;
    for (let i = 0; i <= 6; i++) {
        if (i == 6) {
            while (n < 3) {
                str += `Let's go hunt, doo doo doo doo doo doo\n`
                n++
            }
            str += `Let's go hunt!\n`
            str += `Run away,...`
            break
        }
        let k = 0;
        while (k < 3) {
            str += `${arr[j]} shark, doo doo doo doo doo doo\n`
            k++
        }
        str += `${arr[j]} shark!\n`
        j++
    }
    return str
}
babySharkLyrics()
