go to the 2nd tunnel underground, jump over 2 turtles, collect 40 coins then GROW UP.
you have to hit the ball in the pipe and it appears on the other pipe.
Go to 5-1 after you get dottie. At the beginning go all the way right, use dottie to go through the tunnel and the whacka and a pipe are there. Hope you find it OK!
Jump on the pipe and press down.
Yes - you can blow the engine
Just walk into it
Pen stock is made of pipe while Tunnel is not a pipe.Tunnel is made of concrete material.
As Mario, you need to use the pipe that's located above the second mechanical bird helper. you can get there by warping to "sparkleton 2" and follow the path to the opening with the pipe. AS MARIO press A and it will take you to a close by pipe and you will be right in front of the ice wall :)
Mario came from a green pipe he went in while fixing it with his brother luigi to a place now called mario
The exhaust on most small engines is a standard pipe thread , that goes inside the exhaust port . You can go to any plumbing supply store and get your pipe .
there is a secret pipe, it is in the floor try to find it by pressing down
