Baby Plum is a boss added in The Binding of Isaac: Repentance that can appear in all environments of Chapter 1 (Basement, Cellar, Burning Basement).

Behavior

Baby Plum floats slowly towards Isaac and performs the following attacks:

• Spits a diagonal stream of projectiles, propelling herself backwards across the room and bouncing off any walls she collides into.
  • Randomly scattered in the stream are larger projectiles that deal a whole heart of damage.
  • Baby Plum takes increased knockback from any source during this attack.
• Twirls towards Isaac, sending out a spiral of projectiles.
  • The spiral will always start pointing down, then make a full rotation starting in the direction closest to Isaac.
• Slams the ground, firing two rings of projectiles outwards and leaving behind a small pool of Red Creep. The inner ring consists of 14 slow-moving projectiles while the outer one consists of 8 fast-moving projectiles.
  • The outer ring's projectiles will always be fired in the cardinal and ordinal directions, while the inner ring's projectiles will have a random spread.
• Upon death, releases a ring of 10 projectiles.

Notes

• Rather than chasing Isaac directly, Baby Plum chases a point that orbits around him, causing Baby Plum to fly towards him at a slight angle. It also means that Baby Plum will not touch Isaac if he's standing still unless she twirls at him or bounces around the room.
  • This behavior can also be observed by the boss' familiar version, Fruity Plum, when it is following Isaac.
• If Baby Plum doesn't take damage for 30 seconds, she will wave at the screen before flying away. The Boss Room item that spawns when the room is cleared will also be replaced by Plum Flute if Isaac isn't already holding it.
  • This does not apply in Greed mode, or any rooms she appears in that are not actually her own boss room.
  • Baby Plum can take damage and still give Plum Flute; it just refreshes the time limit for her to fly away.
