A 9 year old is a wild beast. they can usually be found:
*Infesting Fortnite, trying to get a close-range kill with a sniper rifle.
*On Youtube, making a 5 subscribers special.
*Playing Minecraft, screaming ear-piercingly loud about how they found diamonds.
*Hiding in Roblox, waiting for someone to come out of the museum in jailbreak.
*Dabbing. this is actually the most common activity of the wily 9 year old.
*Trying to make friends on Animal jam, unaware that the game would be dead if national geographic didn't sponsor it.
