GB Bug is an unlockable passive item added in Afterbirth.

Effect

• Spawns a familiar that bounces around the room, deals 8 damage per tick or 120 damage per second and applies a random status effect to enemies it comes in contact with.
• The familiar also has a chance to re-roll pickups that it passes over into other pickups, chests, or items, in an uncleared room only (with at least one enemy alive).

Notes

• GB Bug can block projectiles.
• GB Bug does more damage per second than The Peeper, with the added random status chance.

Trivia

• This item's in-game appearance may be a reference to "Missingno.", a famous bug occurring in the first Pokemon games.
• As Edmund confirmed on twitter the pickup quote "Game breaking bug, right away!" is a reference to a quote by Phil Fish in Indie Game: The Movie, where he says the exact same words when a bug is discovered in FEZ on the first day it is being shown at PAX.
