Trivia

 * The mem cakes resemble erasers, specifically the kind that are shaped to look like certain things. This could be a reference to the fact that Agent 8's memories have been "erased" (whether or not they were deliberately erased is unknown).
 * All Mem Cake descriptions are written in poems, following the format; A, BB, A.
