A very thin and dark colored mushroom.
Isaac's head becomes smaller, though, like the other mushrooms, his hitbox is not affected.
- Cancer - Breaks the default rate of fire cap, giving Isaac a very high fire rate.
- The Muligan - And other "effects on hit" items due to the high fire rate.
In Rebirth, Odd Mushroom (Thin) can be found in the first treasure room using the following seed(s):
- L4QE 2MJR
