How do you get to skytown in dizzywood

You get there from the cannon in PRESTO'S EDGE But first the cannon must be charged with the Zap power. You can do this if you have the zap power or you can ask someone else to zap it before you go in. If it is charged, you will go to Skytown after stepping inside the cannon. If not, you will land back down in Presto's Grove.
