Using the Cheat Engine, Old Man Keeper was playable since the initial release of Afterbirth. However, he was invisible as he had no sprites and he started with zero health. These graphics were added in later patches and remained in the game until they were replaced by the real Keeper sprites after the ARG had ended.
If the player played as the Keeper on April Fool's Day 2016, the sprite was changed to this sprite, but only for a day.
