How to Find the Secret Fusion Cave in Steal an Egg
Reach the Secret Fusion Cave in Enchanted Forest with 50B Speed and the Banjo Bat, trigger the melody bridge, and access the new Fusion Area.
The Secret Fusion Cave is a hidden Enchanted Forest route that gives access to the new Fusion Area. You need 50B Speed to access this area and the Banjo Bat to reveal the bridge into the cave.
The Banjo Bat is a required item, not an optional cosmetic. If you do not have it yet, complete the Mushroom Secret Cave route first; it also rewards an exclusive Egg.
Requirements
| Requirement | Why you need it |
|---|---|
| 50B Speed | Required to access the Secret Fusion Cave area |
| Banjo Bat | Plays the melody that reveals and extends the bridge |
| Access to Enchanted Forest | The route starts behind the boss in the new biome |
Step 1: Enter the Cave Behind the Enchanted Forest Boss
Go to Enchanted Forest and enter the cave located behind the boss.
Step 2: Go to the Staircase Around the Altar
Inside the cave, head toward the staircase surrounding the altar.
Step 3: Reach the Top and Find the Hidden Area
Climb to the top of the staircase. You will see the hidden area ahead. Before continuing, make sure you have the Banjo Bat equipped or ready to equip.
If you do not have the Banjo Bat, follow How to Find the Mushroom Secret Cave. That guide explains the player-specific mushroom minigame that unlocks the reward.
Step 4: Equip the Banjo Bat and Reveal the Bridge
Stand near the edge of the platform facing the Secret Fusion Cave, then equip the Banjo Bat. A colorful melody begins to play and a bridge extends from your platform toward the hidden cave.
Wait until the bridge is fully formed before crossing it. Once it is complete, walk across and enter the Secret Fusion Cave.
Step 5: Enter the New Fusion Area
Cross the bridge and enter the hidden cave. This area gives you access to the new Fusion Area.
The Fusion Area includes the Spirit World Guardian recipe: use Celestial Sunlion on the yellow pad and Royal Skywhale on the blue pad to obtain the Divine pet through the two-player sequence. Read Spirit World Guardian Steal an Egg for the exact requirements, stat-transfer rules, and one-time Fusion warning. For the earlier Secret Shrine fusion system, see How to Get Fused Pets in Steal an Egg; its Eternal and Divine rules should not be assumed to apply to this new area.
