Bugs[ | ]

Bug Bug! (in Rebirth and Afterbirth) Due to the extreme force of multiple simultaneous explosions, it is possible for Bomber Boy bombs (especially when combined with Mr. Mega) to propel Isaac into obstacles or over pits.
Bug Bug! Although Collectible Bob's Rotten Head iconBob's Rotten Head works normally with Collectible Butt Bombs iconButt Bombs, and Collectible Bomber Boy iconBomber Boy has no effect with it, their combination drops the explosion damage by 50%.
