Trivia

 * This item's name and the "personalities" of the probes it summons may be a reference to the Personality Cores from the Portal series.
 * The colors of the probes resembles that of The Twins boss from the game Terraria.
 * The probes spawned by this item are wrapped in cloth similar to what the wears, suggesting a possible link between the two.
