The Shrimp is a sentient, talking shrimp (of species Heterocarpus ensifer) discovered by agents Lucius Sievert and Cadmar on a Zombieland mission. The narration is actually referring to Little Rock, but perhaps the Word World didn't like the insult? The Shrimp now lives in a terrarium in RC 43042 with Lucius and Drew Charles, but is available to be written by anyone.
