Many works of fiction are named using a "Title Colon Subtitle" template. For example, Phoenix Wright: Ace Attorney has this kind of title. Sometimes, however, the subtitle becomes an important part of the original work's identity, and when a sequel is made, a second subtitle is tacked on after the first (like the sequels Phoenix Wright: Ace Attorney: Justice for All and Phoenix Wright: Ace Attorney: Trials and Tribulations). When written out, this looks ridiculous, as you have to use a colon to indicate each separate subtitle. That's Colon Cancer; Oddly-Named Sequel 2: Electric Boogaloo carried way too far.
