"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, while his mouth is open when he screams in pain. Then, Speccy gains a rash on his hands and forehead. Dad wants to know what is going on, to which Angry Kid puts the peanut bag on Speccy's head and says that Speccy is slightly carsick. When Dad demands his son to take off the bag from his head, he becomes shocked at Speccy's deformed appearance. He tells Speccy that he is going to take him to a hospital. Angry Kid then starts laughing at Speccy.
