| 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 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 appear as a regular fingerprint, which, besides the fact that the police are somewhat irresponsible, is possibly the reason why he is hard to catch.
Sal Left Thumb is a dangerous and infamous criminal in Elmore. As such, he has a very abrasive personality - he is more than willing to harm anyone and everyone that gets in the way of his criminal activities. He often taunts his victims, such as when he sarcastically told Gumball and Darwin that he was a charity worker accepting donations, when he was clearly robbing the store, or how he calls everyone a "sucker" when they fall for his tricks.
