Zest Bomb

The Zest Bomb is a fruit in Pikmin 3 and a treasure in. It is a, and in Pikmin 3 Story Mode it can be found in the Tropical Wilds, the Garden of Hope, and the Distant Tundra. In Pikmin 4, it can be found in Serene Shores, Frozen Inferno, and Cavern for a King.

Tropical Wilds
The Zest Bomb in the Tropical Wilds is held inside a Peckish Aristocrab located in the large, shallow body of water filled with Yellow Wollywogs in the northern part of the area. Killing the Aristocrab gives the fruit. Since the crab is usually in the water, it is recommended to defeat it with bomb rocks, as Rock Pikmin cannot traverse through the water. Although Winged Pikmin or Blue Pikmin will usually be needed to retrieve the fruit, the Aristocrab can be lured far enough out of the water to drop it on dry land once it dies.

Garden of Hope
In the Garden of Hope, there is a segment on the side with two sets of elevator platforms. The first set is rather simple, and the Zest Bomb is on a plateau near the platforms. To obtain it, first throw a Pikmin onto one of the two platforms, weighing it down. Next, throw a leader and five Pikmin onto the lower platform. On the opposite platform, throw at least 7 Pikmin on it to rise the other leader up. Switch to the other leader, and the fruit will be easily reachable.

Distant Tundra
The Zest Bomb in the Distant Tundra is within reach from the landing site, but it is recommended that you have rescued Charlie before collecting it. Throw 2 leaders over to the plateau next to the Dodge Whistle. To the far left of the cliff is a Bouncy Mushroom. Throw a leader and a good amount of Yellow Pikmin onto it. Afterwards, the leader will be on another plateau near the landing site with 2 Bearded Amprats and a Citrus Lump. Kill the enemies and proceed to have the Pikmin work on assembling a slope with the nearby stack of hay. Now, with the slope complete, the fruit is able to be reached, by following a narrow path between a wall and a small cliff. An Arctic Cannon Larva will shoot snowballs along this path, so use the alcoves to the left for safety. At the end lies the Zest Bomb encased in a crystal. Destroy it with Rock Pikmin to access the fruit. Alternatively, if you have not rescued Charlie, Rock Pikmin can be thrown from the ledge below, but this is an unreliable method.

Serene Shores
There is a Zest Bomb submerged underwater in the southeasternmost body of water in the overworld, more to the west, and is next to a cluster of Dawn Pustules. It is guarded by a Pricklepuff and four Puckering Blinnows, which should be defeated before attempting to collect this treasure. To retrieve it, you must throw 7 Pikmin at it.

Frozen Inferno
There is a Zest Bomb inside of the Freezecake in the northeastern room of sublevel 3 of the Frozen Inferno. To collect this treasure, you must first defeat the Freezecake, then throw 7 Pikmin at it.

Cavern for a King
There is a Zest Bomb lying in a pond along the western edge of sublevel 19 of the Cavern for a King, next to three Cupid's Grenades and a Blonde Impostor. To collect this treasure, you must throw 5 Blue Pikmin or Winged Pikmin at it.

Trivia

 * If the player obtains a Zest Bomb and a Juicy Gaggle consecutively such that both juices are combined into the same bottle, the resulting combination will be an odd cyan color, as explained here.
