The game's subtitle "Diddy's Kong Quest" is a pun on the word "conquest". However, it is commonly misremembered by players as being the more grammatically correct "Diddy Kong's Quest", so much so that when the game was added to the Nintendo Switch Online service in 2020, Nintendo UK's official Twitter account felt the need to clarify the spelling. However, the game being called "Diddy Kong's Quest" is not a false memory. Prior to release, the subtitle used on an early title screen featured in some trailers and gaming magazines at the time was "Diddy Kong's Quest", even when the final subtitle of "Diddy's Kong Quest" was used in printed text.
