To complete the “Explosions Galore!” side quest in The Legend of Zelda: Echoes of Wisdom, follow these detailed steps:

### Step 1: Activate the Quest
1. **Location**: Dampé’s Studio in East Hyrule Field.
2. **Unlock Requirement**: Complete the main quest “Still Missing” and the side quest “Automaton Engineer Dampé.”
3. **Activate the Quest**: Read Dampé’s journal in his studio to start the side quest. Dampé will ask you to find specific items to inspire his next creation.

### Step 2: Find an Octorok
1. **Location**: Octoroks can be found in various locations throughout the game, including the lava sections.
2. **Task**: Find an Octorok, a creature that spits stones out of its mouth. Octoroks are common enemies that can be found in many areas of the game.

### Step 3: Find a Firework
1. **Location**: Eldin Volcano.
2. **Task**: To find the fireworks artisan, you need to complete “The Rift” on Eldin Volcano.
– **Getting to Eldin Volcano**:
– If you have access to Kakariko Village, warp there and head north following the main quest path into the volcanic region.
– Alternatively, use a Crawltula to bypass the long, winding roads and monsters, heading north all the way up to Goron City.
– **Mend the Rift**:
– Mend the rift that appeared in Goron City to return it to its original state. This will make Goron City safe, allowing you to visit the fireworks maker, Basa.
– **Visit Basa**:
– Speak with Basa, who lives in the top right home in Goron City. He will start his side quest, “The Fireworks Artist,” which is essential for earning the firework echo.

### Step 4: Complete “The Fireworks Artist” Side Quest
1. **Task**: Complete Basa’s side quest, “The Fireworks Artist.”
– This quest involves interacting with Basa and learning the fireworks echo. Once you’ve completed his quest, you can return to Dampé’s studio.

### Step 5: Summon the Firework Echo
1. **Location**: Dampé’s Studio.
2. **Task**: Summon the firework echo on the pedestal in Dampé’s studio.
– Dampé will confirm that this is exactly what he’s looking for. If you haven’t already shown him the Octorok, do so now to complete your tasks for Dampé.

### Step 6: Complete the Quest
1. **Reward**: Dampé will create an automaton called the Tocktorok, which shoots fireworks at enemies.
2. **Final Step**: With both the Octorok and firework echoes presented to Dampé, he will complete his creation, marking the end of the “Explosions Galore!” side quest.

By following these steps, you will successfully complete the “Explosions Galore!” side quest in The Legend of Zelda: Echoes of Wisdom.
