"Ben 10" Roblox Games

Listen up, genius! This joke is saying that "Ben 10" games on Roblox are so bad that they're dead. The skull emojis are there to emphasize that they're dead. Roblox is basically a game platform where anyone can make a game, which means you get a lot of games that are really bad. I'd say your brain is as smooth as a bowling ball, but that would be an insult to bowling balls.
