It's their vote once the audience narrows it down, isn't it? But yes, they are pretty pointless and annoying.
Adding my guesses:
Peacock is Donny Osmond, no doubt.
I think the Deer is Terry Bradshaw.
I'm on board with Ricki Lake as the Raven.
The Rabbit is definitely one of the guys from NSYNC, I'm just not sure which one (except not JT and probably not Lance since he's a bass voice).
I think the Bee is Gladys Knight.
I don't think that any of them are a Kardashian - if a Kardashian could sing, the momager would have capitalized on that already and she'd be all over the music scene by now. Tori Spelling, Rumor Willis, and LaToya Jackson are better guesses, IMO.
