Creepysoo dropped from the first layer of the underworld all the way down to the ninth layer. He arrived in a putrid world where rotting bodies of the dead are seen. The smell would be unbearable for any normal person as you could see people getting punished trying to gasp for clean air but all they get is foul air.
Just inhaling the foul air makes them taste it and one could see that they do not enjoy it. They could taste it with their receptors and all of them are gagging all the time. Some of these unfortunate souls even clung to Creepysoo's cloak but he just swept their hands away because this is their punishment.
Anyone being sent to the ninth layer of the underworld is not someone that innocent by any means. Creepysoo went to the cave dwelling of the God of Death Ah Puch. This is the only cave dwelling in this death realm, and it is made of the corpses of all the unfortunate souls sent there.
