Portable Sunset

The Portable Sunset is a fruit in Pikmin 3 and a treasure in. At first glance, it appears to be a Love Nugget (which is a tomato), but it is actually a fruit. It produces 2 bottles of juice (one in Ultra-Spicy mode), and is found in two places in either game's Story Mode.

Distant Tundra
The Portable Sunset in the Distant Tundra requires Blue Pikmin to obtain. It is hanging from a branch above a small pond near a Bearded Amprat and a Bouncy Mushroom. By throwing 8 Pikmin onto the fruit, it will fall into the water, and from there, Blue Pikmin can retrieve it. It is advised to bring some Yellow Pikmin to take care of the few Amprats along the way. It is also possible to push the fruit completely out of the water using two Blue Pikmin carrying the body of a nearby Skeeterskate if not enough are available.

Twilight River
The Portable Sunset in the Twilight River is found right beyond a bamboo gate on the second half of the area. This fruit is guarded by three Orange Bulborbs. If you do not have enough Winged Pikmin, you will have to go head to head with the Orange Bulborbs. Alternatively, simply throw 8 Winged Pikmin over to the fruit. However, they will not go over the gate, instead going right past the Orange Bulborbs and waking them up, although they will go back to sleep immediately.

Primordial Thicket
There is a Portable Sunset hanging from a cobweb northwest of the center of the Primordial Thicket. To collect this treasure, you must first construct the clay bridge nearby, which requires 75 raw material to build. Then, throw 10 Pikmin at it.

The Mud Pit
There is a Portable Sunset inside of a Bogswallow in the southwestern part of sublevel 2 of The Mud Pit. To collect this treasure, you must first defeat the Bogswallow, then throw 10 Pikmin at it.
