Where are all the Red Coins in 1-7?
When you find the locked door, look up and get the Flashing Eggs. Shoot them at enemies to get a Red Coin from each Egg. At the Goal, pound the red and yellow bridges to break them. Swim and get all the coins there. Then go stand on the highest point on the ramp thing sticking out of the ground, and jump straight up. A Spring Ball will drop down. Jump on it and you will find a hidden area. In the hidden area, go left, stand on the right edge of the Chomp Rock to get it rolling to the right and it will reveal a hidden Winged Cloud. Shoot it with an egg, and it will grow a Beanstalk. Climb the Beanstalk up for four Red Coins.
