I really need help on Digimon World. I keep getting Nemumon and Sukemon..

To get poyomon, just choose the orange striped egg when ur digimon fades away.

To get to trash mountain go to savannah gear and find a black ramp, go up the ramp and u will be in trash mountain.

I know I found that today as I was playing.

Numemon and Sukamon? If your digimon evolves into that, it means you don't care about your Digimon. To prevent getting Numemon, take care of your Digimon. (Eg:- feed him, let him rest when tired, let him sleep, train him normally, etc...). To prevent getting a Sukamon, don't let him poop on the ground, let him poop on the toilet. You have to go near the toilet to do that.

1.Firstly to avoid getting Numemon avoid making your rookie digimon's happiness very high while the discipline is very low and don't let your digimon poop on the ground.Secondly to avoid getting Sukamon don't fill the Virus Meter in the condition to it's end and in case if you get him go to Trash Mountain and go to the King Of Sukamon which will return your Sukamon to your digimon which evolved to Sukamon.

2.First begin from Mt.Panorama then go to Gear Savanna.Then keep going all the way north until you find a screen then go to the east to another screen then from that screen also go east.From the next screen you will find a black metal slide inclined.Walk on it and you are in Trash Mountain.

3.The ghost digimon is Bakemon and not Poyomon ashes and in case if you meant Poyomon choose the yellow egg and if you meant Bakemon then I don't know the exact stats to get him but go to Drimogemon in the city and choose the special plan and give him 5000 Bits and after 10 days return to him and he might give you a Torn Tatter which will digivolve your digimon to Bakemon.
