Collecting all 8 Red Coins in the Coral Reef
Firstly, you’ll need to make your way down the beach towards the beach hut at the end as this is also where the coral reef is located.
The 1st red coin is between the orange and pink anemones near the front of the coral reef, and then if you swim into the crevice, the 2nd red coin is hidden in the pink seaweed. To the left of this small section of the coral reef, you should be able to spot a small school of red fish swimming around. Hidden between those fish is the 3rd coin! The red coin will try to swim away from you so you’ll need to be quick!
Now, swim to the right to the other section of the coral reef. Next to some blue anemone, you can find your 4th blue coin. Then, just a short distance up ahead you can find the 5th red coin between some red seaweed. Nearby, there is also another school of red fish swimming around with the 6th red coin! Once again, the red coin will try to swim away!
Swim down to the right through the crevices in the coral and you should find the 7th coin in a small alcove, amongst some orange seaweed. Then the 8th and final coin is located just south of the alcove, between some more pink seaweed. The Shine Sprite will spawn above the coral reef and you can grab it by swimming up to the surface.
