Stories for "Plop!" were generally created in one of three ways. The most common was that Steve Skeates would write the stories himself, using the full script method. Due to a brief feud with editor Joe Orlando, for a time Skeates' stories were written under the pseudonym Chester P. Hazel. The second way was using plot ideas submitted by readers of the anthology. Orlando would select which plot ideas would be used and Skeates would then write the full story. The third way was that Aragonés would write the plot, and someone else would write the script once the story was fully drawn.
