Patrick Mahomes and Brittany Matthews are expanding their quarantine video collection beyond at-home workouts.

On Sunday, the girlfriend of the Chiefs quarterback shared a clip from their latest indoor adventure, attempting the “koala challenge” on Instagram.

“Koala Challenge.. First attempt, there will be more,” Matthews captioned the nearly 93-second video, in which the certified personal trainer climbs the 6-foot-3 quarterback like a tree in a variety of ways before — spoiler alert — falling off.

After Mahomes walks away from the camera’s view, Matthews replies: “That’s so hard.”

This year’s Super Bowl MVP and his longtime lady love aren’t the only celebs who gave the “koala challenge” a shot. Over the weekend, Kaley Cuoco and husband Karl Cook proved practice makes perfect — even on the 246th try.

“After 245 failed attempts we finally did it! LOL the koala challenge is not as easy as it looks. Actually we made it look damn near impossible LOL good luck!!” the former “Big Bang Theory” star posted to Instagram.
