The Pair of Eyeballs is a pet-summoning item dropped by The Twins in Master Mode with a 25*1/4 (25%) chance. It summons Rez and Spaz, miniature versions of the The Twins in their first form.


  • Unlike the Suspicious Eye, Rez and Spaz do not change phases. They are also smaller than the Suspicious Eye.
  • The item tooltip is a reference to the phrase two heads are better than one.
  • The buff tooltip may be a reference to a commercial by the American contact lens retailer 1-800 Contacts.
  • The Pair of Eyeballs is the only pet-summoning item that spawns two pets instead of one.
  • The names Rez and Spaz are abbreviated forms of The Twins' individual names, Retinazer and Spazmatism.
