To get to the hidden town in the game, first beat the last boss. 
Then, go to Mokeke forest in the Underworld. Find the Impact rock, 
then keep going until you see a pink-suited clay doll. Defeat it 
and go left to the player change platform. change to Sasuke or Yae, 
go left, dive, and swim right until you can surface. There is no 
Teahouse in Creep village, so change to whoever you want to be NOW! 
Then, go right until you see a run-down bus shelter with a post nearby, 
and stand under the post. Sometime near daybreak, a HUGE bus will 
come and bring you to creep village. In Creep Village, you can get 
the last 4 entry passes.
