| Sal Left Thumb
| Character Information
Sal Left Thumb resembles an over-sized, sentient fingerprint. He usually is seen wearing a domino mask, likely to keep his identity a secret. His teeth are sharp and pointy, but are somehow straight occasionally. His limbs are very long and skinny, and are rather small compared to the rest of his body. He possesses the ability to flatten himself on the ground and just appear as a regular fingerprint.
Sal Left Thumb is a dangerous and infamous criminal in Elmore. He seems to be very blunt about his "job" and is ruthless as well. He can also be a very sneaky liar, such as when he deceived Gumball and Darwin into working for him; though this could also be because of the pairs' stupidity.
