In Woodfall, a blue chu chu replaced the deku baba that you're normally supposed to kill to get a fairy. The chu chu kept respawning when killed, so the fairy never came out.
In Woodfall, in the room where you were supposeed to kill the Boes to unlock a fairy chest, the boes were replaced by some white/black boes that kept respawning when killed, making the fairy chest impossible to get.
