I have 3 wiggler pieces can't find the 4th piece and it isn't showing up..

The fourth segment's first location is in World 3-11, known as Holey Thicket. To get to World 3-11 you need to knock down the bowling pins in World 3-4. To knock down the bowling pins you need the Bowling Ball which is in World 3-2. In World 3-2 use this route to get to the Bowling Ball: right,left,right,right,right. Then jump the fence in the middle in an upward position. Turn the Bowling Ball into a sticker and then go to World 3-4 to use it and knock down the bowling pins. Once this is complete you can go into World 3-11, where the fourth Wiggler segment is located.

(go to world 3-4 strike lake) -follow the path and look for the area behind a tree you will need a bowling ball for this in the froest in (Baffle wood's) it's... (right/left/right/right/right/up/up)
This is normally when you find the 3rd wiggler part..
After getting the bowling ball go back to (strike lake with the bowling ball "as a sticker" then use it in the bowling ball path follow the next world you see blofinsh the blopper's taken wiggler part 4 to (white cap beach) finsh the world frist to the 2nd "star mark not the frist" then go to the beach and battle the wiggler body~

^^ hope this helps
