Shrimp Worlds refers to two dimensions, which are primarily identified by the amount of shrimp which live there. Specifically, these two dimensions are: * World Without Shrimp is a quiet little agrarian world, with little unusual properties except the absence of shrimp. * World With Nothing But Shrimp contains literally nothing other than shrimp and as a result is sometimes considered boring. The two dimensions can be used to illustrate the concept of alternate dimensions.
