The last site of sunlight on your journey. Named after the numerous bright pink colonies of coral that form below its water's surface, Rosa Reef is a warm, tropical, and mostly welcoming environment. The surrounding land is covered mostly in white sand beaches that are well grown with thick beach grass, and palm trees not too different from the ones growing in the eponymous oasis.

Not only has the reef become an excellent spot for local wildlife: mainly cheep cheeps, lava lotuses, kelp, urchins, and especially coral, but it has also become a very popular migration spot. Migrant species from the Sparkling Waters close to the Mushroom Kingdom, as well as Sarasaland and Dinosaur Land have all been spotted here.

The less dense portion of the reef is also home to the Rosa Harbor, which unfortunately may bring in some complications as ships looking to unload at the harbor tamper with the shallow waters that Rosa’s corals need so desperately to survive.

3-1 Huckit Crab’s Rosa Resort

After a long, mass-migration from the Sparkling Waters somewhere near the Mushroom Kingdom, massive groups of Huckit Crabs worked long and hard together using their singular claws, rocks, and palm wood for construction to build their very own boardwalk village along the waters of Rosa.

They built it along the portion of the reef where there are some large water geysers, assisting transport across the village. Goombas and Koopas helped the Huckit Crabs build their resort, so they have allowed both species to live among them.

The resort is built entirely on palm wood boardwalks, so it is all suspended over the ocean, but with the backdrop of the local palms, and some nearby waterfalls. All of the residents live in thatched-roof bungalows complete with chimneys. If the residents are polite enough, perhaps they’ll let you enter their bungalows. They may even let you visit the resort gift shop, if you explore the resort well enough. You may never know what you’ll find beyond a waterfall.

3-2 Yurarin Trouble!

Rosa Reef’s Harbor has taken architectural inspiration from the more metallic architecture of Sarassaland’s Muda Kingdom. As a result, migrant schools of torion have arrived at the harbor in recognition of the familiar architecture.

These migrating torion schools have caught the attention of the yurarin boos, the seahorses that love to snack on torion. As a result, schools of them have also migrated to Rosa Harbor to seek their prey. They ended up finding most of the torion, and eating all of their flesh, but leaving behind their skeletons and eyeballs.

The end result is a bunch of honen, the undead torions that like to jump up and down from the water’s surface.

However, the honen are fairly harmless in comparison to the yurarin boos. Unlike your encounter with them in the Muda Kingdom, these aggressive seahorses do not like to be jumped on. But, they still love to shoot projectiles at their opponents.

Meanwhile, the Koopas at the harbor have carried on as normal. Many of them are fascinated by the chainlink fence installations, which they have used to hone in on their climbing skills, and entertain themselves along the harbor when no shipments are coming.

3-3 Ultraviolent Dolphins

The dolphins living around Dinosaur Land have found it difficult to swim and play in the minimal amount of water that they have found suitable around Vanilla Dome and Chocolate Island, so they have migrated in search of more expansive, visually interesting water to play around in.

They ended up arriving at Rosa, as the several buoys installed along the surface of the reef caught their eye. Many dolphins have resorted to mostly jumping and playing around those buoys for now.

Many of those dolphins are still completely harmless, but some of them have adapted a new adaption: spikes for defense, as well as a brighter color scheme to show that they mean business. Don’t mess with the spiky dolphins.

Also, everyone’s greatest fear from Desert Land, the Angry Sun is here again. They have returned once again to bring their ultraviolence onto the player. Jumping across dolphins can never be too easy, it would seem.

3-4 Rosa Reef’s Urchin Takeover

The Angry Sun has seemed to become sedated as the hours of night approach closer and closer.

In the meantime, urchins have become an invasive species along the reef.

While the reef is still perfectly healthy and lively, the urchins have seemed to reproduce too quickly, allowing too many of them to munch away at the several blades of kelp once there, and perhaps at many of the local cheep cheeps and coral next. The cheep cheeps have seemed to consider the rise in numbers of their spineless predators, so many have seemingly begun swimming closer to the surface, or jumping up and down constantly along the reef’s surface to try and get away from the urchins.

The madlad wasn’t much of a threat back at Palma, so, in a vain attempt to make Boom Boom more of a challenge, Kamek has used his magic to double the size of Boom Boom, who’s waiting for you at the banks of the reef where many cheep cheeps have went into protection mode.

3-BS King Bob-Omb Switches It Up

Many large ships have appeared to come into view along Rosa Reef’s warm surface. However, these ships don’t seem to have any intentions to go to the harbor.

Instead, King Bob-Omb is still embarrassed by his swift and easy defeat back at his battlefield all those years ago. Fortunately for him, Bowser has given him a second chance to take down the player.

King Bob-Omb wants to make sure he doesn’t fail so soon this time, so he has decided to switch it up… literally. His armada of bob-omb-manned battleships is also equipped with several On/Off switch puzzles, complete with burners for extra flair on his wooden ships. You might have to sacrifice King Bomb-Omb’s henchmen just to get to him. Bombs away!
