In the Star-Crossed World DLC for Kirby and the Forgotten Land, you get to unlock new quests that take you around a new underwater area. Along the way, you will meet new friends and new enemies, and new challenges to take up. Once you reach Fallen-Star Beach, you get an objective to locate 7 treasures in the ocean. This guide will detail where to find them in Kirby and the Forgotten Land.
All Treasure Locations in Kirby and the Forgotten Land: Star Crossed World
Once you get to Fallen Star Beach, you get 5 unique objectives to clear here, one of them being “Find 7 Treasures in the Ocean”. Fallen Star Beach is the third stage in the game and unlocks right after completing Lost in Alivel Mall.
Most of the treasures are hidden, making it hard to spot them in the open. But, with some careful exploration, you get to uncover them and add them to the objective. Below are all the 7 spots you need to check to get all the treasures and complete the objective.

After the meteor hits the water, jump down to the ocean bed and check underneath the newly exposed coral. There is a treasure chest here containing the first treasure.

As you keep exploring the stage, you will encounter a seal that will hit you with its ball. Defeat the seal to get to the switch on the far right side, then make your way up to the second treasure chest to get the next treasure.

The next location to check is where all the switches are surrounded by a few crocodiles in the water. Use Fleurina’s storm ability to jump across the water and bypass all the crocodiles to activate the four switches. After activating them, a new platform will appear on the left.
Get on it and collect the gem, then get on top of the smaller platforms to activate the switch. This will reveal a path to the treasure chest. Use the storm ability again to glide across and collect the third treasure.

From the third treasure chest, glide across to the sandy platform ahead and blow away all the sand dunes using Fleurina’s storm. This will reveal the fourth treasure chest with the fourth treasure.

After collecting the fourth treasure, jump up and go to the right side. Use the storm ability to chip away at the waterfall, revealing a secret room. Inside this room is where the fifth treasure is located.

After turning into a gear cog for the very first time, you will spot a chest to your immediate right after climbing to the top of the wall. Unlock it to get the sixth treasure.

Once you reach the platforms at the top and the advertisement board here, to the left of the trumpet-shooting enemy is a weakened wall. Break through that, and you will spot the final treasure chest.
Kirby and the Forgotten Land’s Star-Crossed World DLC will give you the much needed closure to the end of this platformer game. There is a lot more to explore and new areas to uncover, and you might end up finding new secrets within too.
