You must save Waddle Dees from malevolent forces as you clear the stages of each territory in Kirby and the Forgotten Land and move on to the next territory. Out of 47 Waddle Dees to find in Everbay Coast, there are 11 you can get to fully complete the area's last stage, Fast-Flowing Waterworks. Clear every mission on the stage to save them all, including the five hidden Waddle Dees.
Where are the five hidden Waddle Dees in Fast-Flowing Waterworks?
Begin the stage and head into the water! Note that if you've already saved hidden Waddle Dees, they will appear instead as red Star Coins.
Hidden Waddle Dee #1
The first hidden Waddle Dee can be found easily enough as you are flowing down the course. It's gripped by a blackbird flying under the middle of three cement rings lined diagonally.
Hidden Waddle Dee #2
Find and activate the bomb switch immediately after vanquishing the enemies in the trapped pen. It's next to an old red locker on your right. Striking it will reveal a hidden entrance on the left.
Inside, you'll find a short obstacle course in which you'll need to blow yourself down the water with Ring Mouth Kirby, smashing into the cracked walls to the second Hidden Waddle Dee within the time limit. Choose the correct cracked walls to break past to make it in time. First, break through the wall on the right, then move over and break through the wall on the left. Last, break through the middle wall and charge through the blocks and crocodile enemies to your captive friend.
Hidden Waddle Dee #3
For the third Waddle Dee in the next area of the stage, you'll need the Ice Copy Ability, so, first, inhale the Chilly enemy. Use Stairs Mouth Kirby to put the staircases against the ledges to get farther along and press the switch beneath the burning logs to raise a platform up through the water. Walk Stairs Mouth Kirby across the platform, and leave the staircase on the other Star Switch to open the gold bars for the third Waddle Dee.
Hidden Waddle Dee #4
You can see the fourth hidden Waddle Dee behind even more golden bars that trapped the third one if you look closely. Use Ice Kirby to blast through the enemies and burning logs to the right and below where the Waddle Dees are trapped. Walk the staircase across the platform using Stairs Mouth Kirby, and leave it on the two Star Switches to clear the gold bars and the fourth hidden Waddle Dee.
Hidden Waddle Dee #5
Now, take the door to the next area and skate along the water, pushing switches to break through boxes. You'll pass one large whirlpool and finally arrive at the second, larger whirlpool when you'll see the fifth hidden Waddle Dee floating above the center of the vortex.
Cross to the right and go up the stairstep ledges. Push the Star Switch, and block platforms will appear for you to save the fifth and last Waddle Dee of Fast-Flowing Waterworks.
That's all five hidden Waddle Dees! Clearing the stage rescues three Waddle Dees in the first place, finding the three Tins of Fish releases another, winning the battle near the beginning of the stage without falling into the water will rescue one more Waddle Dee, and finding the golden fish will save the last.
