In some small manner of explanation; about Trevor the cupboard Goblin:
Once you open a cupboard containing Trevor the cupboard Goblin, each and every cupboard you open from now on has a 25% chance to contain Trevor the cupboard Goblin. Each time you uncover Trevor the cupboard Goblin, it is the same Trevor the cupboard Goblin as you found last time, the links and events of causality have merely slipped into place to allow him to now be in this cupboard as well.
The only exception, is if you kill Trevor the cupboard Goblin. If you do, the curse is not lifted, it merely develops. If you have killed Trevor the cupboard Goblin, and you open a cupboard that the dice determine contains Trevor the cupboard Goblin, you will find Trevor the cupboard Goblin, alive, and a dead version of Trevor the cupboard Goblin, much to Trevor the cupboard Goblin's dismay. Indeed, each time you kill Trevor the cupboard Goblin, there will be an additional corpse to go along with the previous corpses, and the current Trevor the cupboard Goblin.
Eventually, if you kill enough Trevor the cupboard Goblins, then the mere act of opening the cupboard to reveal Trevor the cupboard Goblin, will generate enough Trevor the cupboard Goblins that the living Trevor the cupboard Goblin will be killed under the weight of all the dead Trevor the cupboard Goblins. Thus, from now on, each cupboard that you open has a 25% chance to contain a increasingly large pile of dead Trevor the cupboard Goblins. From this point on, each time you discover such a pile, there is a cumulative 1% chance that the act of opening the cupboard releases such a pressurised release of Trevor the cupboard Goblins that the impact buries and suffocates you under a karma-fuelled tide of green goblin flesh.
And you would deserve it. Dick.
