This is my prediction for 31. 31: He is inspired by and based off of Mokey form Sr Pelo's Mokey's Show. He is really expressive and exaggerated. He also loves Christmas. Other numbers get startled by his scream. He shows an extreme hatred when others deny for what he affirms. He and 3 are rivals for who is louder. BUT... Other than the other numbers, 31 can speak English like a human.
