Walnut 
Effects
- After Isaac is hit by 1-9 explosions, the Walnut will be destroyed and spawns a coin, a heart, a key and another trinket. The pickups may be of any normal variety.
Notes
- Taking damage from the explosion is not required to trigger the effect.
Synergies
- (Bomber Boy) Bomber Boy: As Bomber Boy causes 9 explosions at once, laying a bomb and not moving before it explodes will always trigger the trinket.
- (Gnawed Leaf) Gnawed Leaf: Isaac will not be knockbacked from the explosions, but it will count for the trinket.
- (Host Hat) Host Hat / (Pyromaniac) Pyromaniac: Not only will Isaac become immune to explosions, but the amount of required hits is reduced to 1-5.
