WATCH: Kostyuk gets up to hijinks with little sister

The coronavirus shutdown of the tours has meant more family time for (almost) everyone. Coco Gauff has been making TikToks with her little brother, and Caty McNally and Alex de Minaur have also been dancing up a storm with their siblings.

And then there's Marta Kostyuk. The 17-year-old Ukrainian and her little sister Zoryana have been keeping their competitive spirit alive, to say the least:

The rules were simple: slam the pad first and guess the song correctly. Both sisters were impressive with their knowledge of song names, while the younger Kostyuk was the more expressive and aggressive one.

The sister hijinks didn't stop there as nine-year-old Zoryana got a little scissor happy during quarantine.

She's also a tennis player, perhaps hoping to follower in her sister's footsteps.

Marta is currently ranked No. 141 in the world, and enjoyed a memorable run to the third round of the Australian Open in 2018 when she was just 15. She won her third career ITF title (a W60 in Cairo) just before the tour shutdown.
