To get the plunger shoes you have to go the Chuffy the Train, defeat him, then go to Grunty Industries and open the trin switch.
Then go back to Chuffyand inside him there is a button that says 'go' stand on it and press 'b' and it comes up with a list of places you wanna go.
In it should be grunty industries and you press 'a' when it is highlighted. Then Chuffy will take you inside Grunty Industries, and you open the front door from the inside and the plunger shoes learning pad is on the first floor somewhere. There you go!!!!
