Find the Decorative Heal Ball in Babby Basin by digging beneath the seafloor beside a hidden house. The item is stored in a secret room and is required for the Mermaid's Gym habitat.
Quick answer: Start playing in Babby Basin and travel to the small house beside the tall red building and nearby bridge. Dig directly next to the house on the seafloor, enter the room that appears below, and collect the Decorative Heal Ball from the pedestal.
Before You Go
The Decorative Heal Ball is located underwater, so you must first gain access to the seafloor in Babby Basin. The Dive ability from Manaphy lets you move through the submerged section and reach the treasure area. Once you can dive and dig, no additional special tool is needed to open the hidden room.
Find the Landmarks
Three nearby landmarks identify the correct location. Use the tall red building, the bridge, and the small house to confirm that you are in the right part of Babby Basin before digging.
| Landmark | Purpose |
|---|---|
| Tall red building | This is the main reference point for locating the area. |
| Bridge | The nearby bridge confirms that you have reached the correct section. |
| Small house | The Decorative Heal Ball is buried directly beside this house. |
Dig Up The Heal Ball
Reach Babby Basin. Move toward the tall red building, which is the most visible landmark in this section. The bridge and the small house should be close by once you reach it.
Locate the small house. Check the area beside the tall building and bridge until you find the small house. This structure marks the exact position of the buried secret room.
Dig beside the house. Use the Dig ability on the seafloor immediately next to the small house. The correct spot opens an entrance to a concealed room beneath the seabed.
Enter the hidden room. Drop through the opening and walk to the pedestal inside. Take the Decorative Heal Ball resting on top to add it to your collection.
Confirm The Pickup
When you collect the item from the pedestal, Pokémon Pokopia displays the message, “You found someone's hidden treasure! It's a decorative Heal Ball!” The Decorative Heal Ball then appears in your inventory as one item.
Use The Decorative Heal Ball
The Decorative Heal Ball is one of four decorative Poké Balls needed to build Mermaid's Gym in the Bubbly Basin habitat. This is the habitat that spawns Starmie. You must place the Decorative Heal Ball with the other three decorative balls, one Marine Sofa, and six Pedestals to complete the build.
| Mermaid's Gym requirement | Amount |
|---|---|
| Marine Sofa | 1 |
| Pedestal | 6 |
| Decorative Great Ball | 1 |
| Decorative Heal Ball | 1 |
| Decorative Dive Ball | 1 |
| Decorative Net Ball | 1 |
| Pokémon spawned | Starmie |
Get Another Copy
If you miss the pickup or still need another decorative ball, the Pokémon Center's 3D printer could recreate the missing item. First, you must obtain a photo of that item from a friend's game or from a cloud island. The photo lets you print a replacement and provides a reliable way to finish Mermaid's Gym without searching for every decorative ball again.
