"Swollen" is the 11th episode in Season 2 in Angry Kid.
Angry Kid and Speccy are sitting in the back of Dad's car. Angry Kid offers Speccy a peanut. Speccy says no, because he is allergic to peanuts. Regardless, Angry Kid then makes Speccy swallow a peanut by punching Speccy on the shoulder, and while Speccy's mouth is open when he screams in pain, Angry Kid shoves a peanut in his mouth. Then, Speccy becomes completely deformed when Angry Kid takes the bag off him, and Dad tells Speccy that he is going to take him to a hospital. Angry Kid then starts laughing at Speccy.
