Carbon Costume sml
Jeffy from SML
In the YouTube series SML (formerly SuperMarioLogan), Jeffy Jeffy is the adoptive son of Rose and Marvin, who he spends his days annoying. He wears a blue helmet and has a shirt with his name written on it by his mom… so he won’t forget his name. To fully commit to this costume you’ll want to keep a pencil (the rubber variety is recommended for safety) shoved up your nose, and diapers worn outside your pants. The better to keep your diaper clean.
