When Kwazii and Dina find an ancient treasure map, they set off to find the hidden treasure of the Lost Coral City, but they'll have to deal with traps, monsters, and mysterious puzzles first.
The episode begins with Kwazii and Dina having their rematch. They see something on the ocean floor, go up to it and see it is a paper inside a bottle. Kwazii opens the bottle and takes the paper out before unrolling it. The two look at it and notice it is a treasure map.
Kwazii: It's a treasure map for the Hidden Treasure of the Lost Coral City.
Dina: Cool. Should we follow this and find the treasure?
Kwazii: That sounds like a good idea. Let's do it!
(Kwazii jumps back in the Gup B and he and Dina start their journey. They follow the map up to a very dark cave and Kwazii pulls out a flashlight. The entrance is too small for the Gup B, so they leave it. While in the cave, they run into a three-headed monster that starts chasing them. After escaping the cave, they run into a blockage. The blockage prevents the monster from getting in.)
Dina: Whoo! That was too close for comfort.
Kwazii: Aye, matey.
(The two notice a temple in the distance and the map says they must reach it.)
