Unlock Up to Level 6 Realm Challenges

Progress through Together in the Cloudsea to unlock increasingly difficult Realm Challenges. There are a total of six challenges, and each level introduces tougher enemies, more complex mechanics, and greater rewards. As you advance, you'll need to optimize your strategy, coordinate with allies, or master solo tactics to overcome these escalating trials.
Follow the Bubble Trails

As you explore the realm, you'll encounter pink and blue Bubble Trails. Each bubble color corresponds to a hidden path of the same hue. When you activate a bubble, it will reveal a hidden platform or invisible walkways. The challenge lies in the timing and knowing when to switch between bubbles to uncover the correct path forward.
Cloudsea Realm Challenge
Stage I
Use Bubbles to Show Platforms
Approach and interact with these bubbles to activate them. Upon activation, they will reveal or highlight the hidden platforms nearby.
Watch Out for Over The Edge Bubbles
In the Cloudsea Realm, certain bubbles are strategically positioned at the very edges of platforms or suspended in mid-air. To reach them safely, you'll need precise timing and smart use of Nikki’s Floating ability to stay airborne just long enough for the hidden paths to appear as any missteps could send you falling into the abyss.
Bubble Trails Has a Faster Switch Mechanism
In Hard Mode, the mechanics remain largely the same, but the challenge increases with shorter delays between bubble activation and platform disappearance. This means you'll have less time to react, requiring faster decision-making, quicker jumps, and even more precise use of the Floating ability to avoid falling or missing platforms.
Stage II
Moving Platforms
In the second stage of the Cloudsea Realm, moving platforms are introduced, adding an extra layer of difficulty. These platforms shift horizontally or vertically, requiring precise timing to land on them as they move.
Check Platform Path Lines
In some stages of the Cloudsea Realm, glowing lines or trails appear as hint to show the path of hidden or moving platforms. These visual cues are essential for planning your next jump and understanding where the platforms will appear or travel.
Watch for Signs They're About to Disappear
Make sure to cross before the platform disappears, as many sections in the Cloudsea Realm are strictly timed. Once a bubble is activated or a platform becomes visible, a hidden timer often begins. These platforms will only remain solid for a few seconds before they begin to flicker, dim, or emit fading particles before they're about to vanish.
Pay Attention to Path Patterns
In later stages, platform path lines lines also intersect, overlap, or form crossing routes, making it harder to immediately tell which route leads forward. You’ll need to study the layout carefully and observe how the paths behave before making your move as sometimes the right way forward isn’t the most obvious one.
Stage III
Vanishing Platforms
Stage 3 introduces vanishing platforms as the main challenge. These platforms appear briefly and begin to flicker, pulse, or fade when they are about to disappear, giving you a moment’s warning to act.
Watch the Chain Sequence
Many of these platforms appear in a timed sequence with a specific pattern, requiring you to observe their order and rhythm before attempting to cross. They often light up or become solid one after another, and following the correct pattern is key to maintaining momentum.
There is No Time Limit So Take Your Time
Rushing in without understanding the sequence can lead to missteps or falling, so take a moment to watch how the platforms behave, then move decisively once the path is clear. Once you've identified the rhythm, you can make your move with confidence and precision.
Pattern Recognition is the Key
If platforms appear in a set pattern or loop, try to memorize the sequence. Watch how each platform activates, the order in which they appear, how long they remain visible, and when they vanish. This helps you anticipate the next move which is especially helpful in Hard Mode, where reaction windows are shorter.
Stage IV
Escort the Bubble to Safety

In Stage 4 of the Cloudsea Realm, fan mechanics is introduced. Your goal is to escort the bubble all the way to the end of the course, so carefully navigating these hazards with precise timing and coordination is needed to complete the challenge.
Bubbles Regenerate at the Recent Checkpoint

If the bubble is popped along the way, whether by wind from a fan or bullets from a cannon, it will automatically respawn at the most recent checkpoint you've passed. Escorting the bubble requires both careful navigation and awareness of these safety points. Use checkpoints to your advantage as you guide it safely to the goal.
Don't Move From The Turn Off Switch Early
To safely guide the bubble past the fan, you’ll need to step onto the switch platform to temporarily turn off the fan. Wait until the bubble has completely passed through the fan’s wind path before stepping off. If you move off the switch too soon, the fan will reactivate, and the gust can burst the bubble mid-transit.
Use Elevation to Your Advantage

Gaining higher ground can make a big difference when escorting the bubble through complex sections. Standing on elevated platforms, ledges, or hovering just above the bubble gives you a clearer view of the route ahead
Scout The Bubble’s Path Ahead
It's a good idea to move ahead the bubble and follow its path line to get a look at the route it will take. These glowing path lines show exactly where the bubble will travel, allowing you to identify hazards in advance such as fans, cannons, or moving platforms.
Timely Use of Multiple Switches
In the final stages, you’ll face sections with multiple switches that must be timed in sequence to guide the bubble safely past hazards. Use the glowing path lines on the wall or floor to predict when the bubble will reach each obstacle, and activate the correct switch just before it arrives. Stay positioned between switches to react quickly while keeping the bubble in view.
Time Movements with the Bubble’s Speed
The bubble moves at a steady pace. Learn its speed and synchronize your movements to be in position for switches or obstacles just as it arrives.
Stage V
Currently Locked

This stage is not yet accessible. Keep progressing through earlier stages and completing challenges to prepare for when Stage V becomes available
Expect Cannons In the Realm

Although introduced in Stage 4 alongside the fan mechanics, cannons weren’t implemented yet and are expected in later stages. They fire projectiles across the bubble’s path, and you must use lift platforms to block the shots and let the bubble pass safely.
Stage VI
Currently Locked

This stage is also currently inaccessible. Once it becomes available, you’ll be able to continue your progress through the Cloudsea Realm.
