Trivia[]
- Corrupted Data is one of the few unlocks for any character that isn't either an Item, Pickup, Character, or Baby, along with Charming Poop, Fool's Gold Rocks, Crane Game, Hell Game, Rotten beggars and Confessionals.
- This unlock is a reference to a bug in computer coding with the same name, which is caused by parts of code being scrambled or missing which often makes the code almost or completely unusable.
