In Ape Escape 2, in "The Blue Babboon" and "Simian Citdel" levels, one-of-a-kind enemies exclusive to each stage can be found known as the "Space Can" and the "Submarine Lookalike" respectively, neither of which can harm the player in any way. Their Enemy Cards both mention that they "came to the wrong game". Ape Escape 2 was developed by Japan Studio and originally released in Japan on July 18, 2002.

A little over three months later on October 24, Sony published a Japan-exclusive game titled Space Fishermen, a collaboration between Japan Studio and the American animation studio Spümcø, Inc. under the name "Land Ho!". Both characters appear in the game as fish you can catch, presumably having found the correct game they were supposed to be in.
