Touch: Kirby help required

[The Mole]

Can anybody give me some tips on how to beat the times in the Stone B challenge(Route to take ect).

Also i am in desperate need to find the red plunger

I would also like to know how to hit switches that are behind walls (without useing bombs) Some of the medals require you to hit a switch that is behind a wall and their is no sight of any bombs.

the walls without bombs usually there is a bomb nearby which when hit makes a spark travel across the screen if you follow this across it will blow the wall up and allow passge.
The stone challenges are by far the hardests of the special stages and tbh only practice and figuring out where the exit is will get the time trials.

I only have two to get in stone b and i have got all the time trial medals.

I still have to find that dam red plunger in the main game though.

Theres no sparks about to destroy the stones any other ideas?
