This Sunday night's episode of Bizaardvark is called "Best Friend Tag," named after the popular challenge video topic!
According to a Disney show description, "When Paige and Frankie invite Amelia over for a sleepover, when they think the DIY diva doesn't have a best friend to tape a Best Friend Tag video. She goes a bit overboard trying to make it perfect. Meanwhile, Bernie and Dirk try to cover up damage from a hapless dare."
In the video, we get to find out how the girls met, some fun facts about what they each keep in their fridge, and what Madison and Olivia's nicknames for one another are!
