In-game Footage[]


  • This trinket is used in Challenge #28 (PRIDE DAY!).
  • Rainbow Worm can't give you the effects of worms you're currently holding (with Mom's Purse Mom's Purse or Added in Afterbirth †Belly Button Belly Button) or ones that were gulped.
    • Therefore, somehow gulping all the worm trinkets in one run makes Rainbow Worm useless.
    • Added in Repentance Rainbow Worm acts as giving a second copy of worms you're currently holding, usually doubling any stat increases of the worm.
  • Added in Repentance Having Mom's Box Mom's Box will double Rainbow Worm's effect, and then also double the two trinket effects it grants, maxing out at triple the effect.
