Pills / Slot Machine

Name	Description
Pretty Fly	Grants 1 fly orbital that circles the player, blocking projectiles and damaging fly-type enemies on touch.

Notes

• A maximum of three Pretty Flies can orbit around Isaac.
  • It is possible to have more than three orbitals if one has access to co-op mode. If a co-op baby or multiple co-op babies temporarily hold all but two orbitals while Isaac picks up another, and then the co-op baby or co-op babies sign out or die, Isaac will receive their orbitals as well.
• Cube of Meat, Ball of Bandages, and Sacrificial Dagger take up a pretty fly slot.
  • For example, If Isaac has three pretty flies and picks up a Cube of Meat, the Cube of Meat will replace one of the flies.
  • Only first and second stage Cube of Meat and Ball of Bandages are orbitals. Therefore, upgrading from level 2 to level 3 will free up a pretty fly slot.
• Duplicated orbitals, such as Forever Alone being copied with the Box of Friends or Diplopia, will fly directly opposite the original (having three copies will cause them to fly 120 degrees apart, four will fly at 90 degrees and so on).

Trivia

• Pretty fly is a play on the phrase "pretty fly" as a descriptor.
