The Bloat

The Bloat is a boss of the The Binding of Isaac game series. He is the posthumous (zombified) version of Peep. He has the same body shape as Peep, but now lacks both of his eyes (which float around his head), has a pale grey skin color, and is bleeding profusely from his eye sockets.

Biography
Immediately at the start of the game, the Bloat's eyes will bounce around the room. Periodically, he'll do a high jump and attempt to land on Isaac, which fires eight blood bullets in all directions. He'll also produce a puddle of damaging blood (or "creep") which surrounds him. If the play brushes to the side of him or in front of him, he'll fire two Brimstone lasers in front of him or to both sides of him from his eyes depending on where the player is. This attack is not telegraphed.

Variations

 * Green: Instead of blood bullets, he'll fire greenish-red explosive projectiles (also known as Ipecac shots in-game) and spawns two Charger enemies whenever he produces red creep.

Trivia

 * The Bloat is one of the most hated bosses among Binding of Isaac players due his battle being considered by most to be tremendously difficult and unfair. In fact, he is so hated in the fandom that this has led to the creation of a subreddit dedicated to ranting on him.
