Powers and Abilities
Both Upchucks' mouths can stretch, allowing them to swallow objects larger than themselves. They are connected with a trans-space bladder dimension where they store all the "food" they eat. He is both connected to the gourmand species and sense any danger to his people through his stomach.
By breathing air out of their mouths, both Upchucks are able to fly.
The items ingested are converted into explosive balls of liquids that can be expelled with great accuracy. Perk Upchuck can also make them curve, like a boomerang, shuriken, or frisbee. Murk Upchuck hasn't shown this.
Perk Upchuck is able to take a surprising amount of punishment for a creature of its size, taking the force of a moving car impact as well as surviving after being thrown through a wall.
Both Upchucks can eat and spit out energy, such as lasers, in the same way he eats and spits out acid matter.
In Duped, it is shown that Murk Upchuck can spit out slime. Perk Upchuck hasn't displayed this.
Both Upchucks have a limit to how many big objects they can swallow at once.
