Tsum Tsums: kids love 'em, parents hate 'em!
If you haven't seen these little worm-like mascot creatures before you will at some point in your life (whether it's due to a future kid, nephew/niece, or what have you). The gist is that they're wildly popular toys that originated in Japan, dating back to a video game (primarily in arcades, then mobile). Since then they've broken out all across the world, becoming a multi-billion-dollar subfranchise.
Now, the worms are ready to hit consoles, but the red carpet isn't fully rolled out yet.
