Plz Help Me with this i dont understand

~Hello!~
I'm just here to help so if I get the wrong answer, please don't be rude and report me for no reason like how others have. :/
Anyways, I think the answer is "around boreal bear blubber" because it's obviously an alliteration. You know this because it has a tone of B's.
Please make me a Brainlist!
