Sunken Treasure
Zora Cape is filled with dangerous Like Likes and Leevers, but they won’t bother you as long as you wear the Stone Mask. Go southwest until you reach the water’s edge, then switch to the Zora Mask and dive underwater.
Use your map to track down a sunken chest to the south. Open it as Zora Link to cash in on a Purple Rupee.
Game of Throws
That Purple Rupee soon comes in handy, for some Zoras have set up a little game back on the beach. Swim back to dry land, and speak with the Zoras to learn the gist of their game. If you can manage to break all of the jars that they’ve set up nearby in one try, you win!
Zora Link’s fin toss is the key to beating this game. Stand before the jars and line yourself up so that, while holding 
to aim, Zora Link’s head is completely covering the central jar. The two nearby palm trees should also be “framing the shot,” with each palm tree just barely visible at the left and right sides of your screen. Once you’re all lined up, release 
to throw Zora Link’s fins.
If you do it correctly, the fins smash through the central jar, split off and break the two rear jars, and then smash the two outside jars as they spread apart during their return trip. It isn’t easy, but a perfect throw earns you 100 Rupees. (Less the 10-Rupee cost of jar replacements, of course.)
Rupees are all that you can win from this game, but you need to beat it if you want to complete your Bombers’ Notebook. If you only break some of the jars, you still have to pay 10 Rupees to replace them before you can try again. Study the fins’ flight path after each throw, and make little adjustments until you find the sweet spot and smash all of the jars.
The Like Like’s Heart
Return to dry land, and follow the trail to the southeast. Keep going until you reach a big waterfall, using the Stone Mask to ensure that the roaming Like Likes and Leevers don’t bother you.
When you reach the waterfall, swap your Stone Mask for the Zora Mask, and then hop into the pool. Move close to the waterfall, and then dive all the way down to the sea floor. Ensure that you’re near the outside wall as you dive, for a dangerous Like Like lurks in the center of the pool.
The Like Like won’t chase you—it remains near the center of the deep pool. However, the current draws you toward the Like Like, so fight against the current and keep your distance. Target the surrounding Skullfish first and defeat them all, holding and releasing 
to throw Zora Link’s fins at them from a safe range.
Now for the Like Like. Stun this item-eating monster by throwing Zora Link’s fins at it from range, then get close and tap 
to hit the Like Like with a single melee fin strike. Flee before the Like Like recovers, then stun it with another fin toss and close in for another blow. Keep it up until you’ve defeated the Like Like.
This reclusive Like Like leaves behind a Piece of Heart and some precious Rupees. Collect these worthy prizes before returning to the surface.
Piece of Heart #29
You got a Piece of Heart! Collect four Pieces of Heart to assemble a new Heart Container. Each new container you put together increases the amount of life energy you can have.
Ledge Treasure
Back on the surface, put on the Stone Mask, and slay the Like Like to the north. Collect the Rupees that it drops, then look up and spy a high ledge with a palm tree. Hookshot the palm tree to zip up to the ledge.
After you land on the ledge, aim south and target another palm tree. Hookshot over to the palm tree to reach the ledge across the trail.
Look up and Hookshot the next ledge’s palm tree to reach a chest. Open it for a Red Rupee.
After looting the chest, zip over to the east ledge, then carefully step out onto a large root. Spot a ledge below you with a Deku Flower, then make a careful jump from the root’s skinniest part to reach it. The Bunny Hood can help you jump farther if you’re having trouble.
Once you reach the lower ledge, put on the Deku Mask and dive into the Deku Flower. Launch out and glide to the north ledge, which features another chest that contains a Red Rupee.
After raiding the chest, Hookshot the lower ledge’s palm tree, then continue using the Hookshot to make your way back around the ledges. This time, aim to zip over to the south ledge near the waterfall. Enter the cave that you discover up there to visit the Waterfall Rapids.
