To participate in the Mango Rush mini-game in The Legend of Zelda: Echoes of Wisdom and understand the prizes you can earn, follow these detailed steps:

### Step-by-Step Guide to Mango Rush

1. **Locate the Tough Mango Lab**:
– The Mango Rush mini-game is located in the Tough Mango Lab at the northern side of the Oasis in the Gerudo Desert.

2. **Meet the Researcher**:
– Inside the lab, you will meet Tourma, a Gerudo researcher who is struggling to keep up with the rapidly growing but short-lived tough mangoes.

3. **Participate in the Mini-Game**:
– For a fee of 10 Rupees, Tourma will allow you to participate in the mini-game. The goal is to harvest as many tough mangoes as possible within a set time frame.

### Standard Seeds (40/50)

1. **Initial Challenge**:
– The initial challenge requires collecting at least 40 out of 50 tough mangoes. This level has no environmental hazards.

2. **Rewards**:

– Reaching 50/50 will reward you with 5 Tough Mangoes.

### Vibrant Seeds (50/60)
