This Croc Will Die in 100 Days (100-nichi go ni Shinu Wani) originated as a viral Japanese webcomic by artist Yuuki Kikuchi, which chronicled the daily, mundane life of a gentle crocodile who was completely unaware of his scheduled death. Published daily on Twitter between late 2019 and early 2020, the series became a massive cultural phenomenon because the audience knew the exact date of the croc's demise while the character did not. In the meme world, this template is used to represent the contrast between blissful ignorance and an approaching disaster or deadline. It is frequently employed to joke about the end of vacations, the arrival of Monday, or any situation where a period of happiness is about to be cut short by an inevitable reality.
