It's February, which means it's officially Rookie season for Red Velvet.

As the South Korean pop group enter into promotional activities for their fourth mini-album, we're taking a look back at all of the troupe's singles over the years: from 2014's "Happiness" to "Ice Cream Cake" off of their 2015 debut EP, to The Red's "Dumb Dumb," to The Velvet's "One of These Nights" to Russian Roulette's title track from last year all the way to "Rookie" this week. But which one is the best one of them all?

Revisit all of Red Velvet's savory selections below — and then place your vote. We'll reveal the winner right here on February 15.
