Intermediate station: Port Prisma
Before going to the Indigo Underground, you must first find Port Prisma and a plunger.
Run to the left and cross the repaired bridge. Speak to the Toad in front of the Toad Town Post Office and enter it immediately. Talk to the Toad again so that he will hand you a few letters and fix the lopsided sign over his shop. Leave the Toad Town Post Office and color the three toads to your left. Stand in front of the Toad Town Post Office again and press the cut button. Draw the line on the Wii-U GamePad, go to the flag and color all the white spots, one of which turns out to be a Toad. Go to the blue color star and learn the card wheel system before you take it.
Return to Port Prisma and head to the café to the left of the Toad Town Post Office. Speak to the Toad who sits on the left folding chair and give him ten coins, after which he will give you a tip. March back to the harbor and walk right past the dark brown barrels. Talk to the Toad that comes out and finally squeeze out the plunger.
Run down the ramp and try to climb into the green warp pipe as well as pull out the stuck toad. Press the Cut button to remove the violet block in the background, and place the pooling card in from Port Prisma to free the Toad.
The Toad turns out to be the leader of the green Rescue Squad. Try to climb into the Warp Pipe again and fight the Shy Guy. Now finally climb into the Warp Pipe and take care of the next Shy Guys. Stand in front of the crumpled paper and smear it with paint until the first rescuer toad comes out.
Continue to the right and let yourself be hoisted up from the elevator. Immediately get on the next elevator and jump to the left. Free the second savior-toad by jumping from below against the swooper and fighting him. Then you can take care of the three swoopers on your own wish, which hang on the Blanket in the lower part of the cave and are best killed with a triple hammer or jump attack.
Go to the stationary elevator and remove the white spot to activate it. Drive up and jump right over the gap to fight against the next swooper trio. Stand on the elevator to your left and enter the secret room hidden behind the wall. Collect all coins and then examine the niche on your right. Wait until the elevator goes up again, and go inside it. Keep waiting until he transports you down and march to the elevators to your right. Let yourself be hoisted from the back to the top and find another secret room behind the wall.
Jump to the platform to your left and go through the passage. Surprise the Buzzy Beetle with a blow to the head and eliminate it best by knockout hammer. The same applies to all other Buzzy Beetles that you encounter in the course of your journey. After a while you reach an elevator, the tape of which you have to remove. In this way, you also free the next green savior-toad.
Run forward and stand next to the bridge to your left. You see on the other side a savior toad, which is followed by numerous Shy Guys. As soon as you jump on the jetty, you throw one of them at you. If you have caught a Shy Guy, you have to fight him. If you hit the Toad, however, all remaining enemies will attack you at once. This may not sound particularly desirable, but you can eliminate the villains in one fell swoop with a serial jump card and then look forward to the next liberated rescuer-toad.
March back to the right and enter the next area. Follow the path until you reach the two waterfalls. Behind the right you can see some shadows, so you stand on the left and press the cut button. The line pattern should now appear exactly above the said waterfall. If not, then you have to take a few steps to the side.
Cut out the waterfall and fight the Shy Guy to free the fifth savior Toad. Follow the path to the right until you hit an elevator. Drive up, jump over the first gap and remove the white spot that graces the elevator. Jump over the second gap and take the coins.
You should next jump into the second gap and land on the block below so that you can color the white spot on the wall. Then move up again and jump from the left into the first gap. You should land in a secret niche, which in turn leads you to a swooper map.
Go all the way to the right, take the elevator up again and enter the niche to your right. Go to the wall and fight the Shunned Guy with a fire or ice flower card. Then color the savior-toad, which is lifeless in the corner.
Turn around until you see all the green Rescue Squad united above you, and talk to the leader. Complete the three Shy Guys and pull the Rescue Squad up. March over them, dye the white spot on the wall and remove the tape. March through the opening and grab the yellow star to your left. This opens the way to Daffodil Peak.Daffodil Peak
Lemon and Color Star #2
Repeat the level and return to the opening of level. Jump carefully to the question mark block that hovers among you and contains a map. March back up, walk past the opening and hit the Lemon with the hammer. Follow down, do the two Shy Guys and squeeze out the Lemon. Finally, enter the rear niche, where there is a blue color star. This opens the way to Bloo Bay Beach, your next destination.Bloo Bay Beach
