New Super Luigi U: Rock-Candy Mines-3 -- Spike's Seesaws

The Spikes in this level make dealing with the seesaws more difficult. The first Star Coin is over the first Spike on the right. Take the seesaw up and go past the Green Ring. There is a Spike standing on some brick blocks. Pound the brick blocks as Super Luigi to find the hidden second Star Coin. The third Star Coin is past the second seesaw that takes you up. Stomp the Spikes and jump to the green pipe overhead. This will take you to a seesaw with a Spike in front of the flagpole.
