Unlocks

Exploration Kit
The Exploration Kit in Pikmin: Wide World consists of upgrades that benefit leaders only; ship parts (listed below this section) also benefit leaders but are applied to the Dolphin Lander instead. The Exploration Kit includes some upgrades from previous games in the Pikmin series, namely ' and ', but also includes some original upgrades as well. Upgrades are not obtained from treasures like they are in Pikmin 2, but instead appear as the upgrade itself encased in a small plastic capsule that must be carried to the Dolphin Lander to be unlocked like in Pikmin 3. Most upgrades are found setting around various areas, but some other upgrades are only dropped by bosses. Each Exploration Kit upgrade requires at least fifteen Pikmin to carry it, and a maximum of twenty-five can be carrying it at once. All Exploration Kit upgrades can be toggled on or off from the HocoPad. All Exploration Kid upgrades are found at tier one, and most of them can be upgraded using Sparklium to increase the benefits they provide.

Ship parts
Unlike the ship parts in  that are used to rebuild the S.S. Dolphin, the ship parts in Pikmin: Wide World are instead used to upgrade the Dolphin Lander. There are only a few ship parts to collect, but each of them greatly benefits the leaders. They are as follows:
 * Repair Module: Allows leaders to repair their spacesuits by standing in front of the Dolphin Lander, on the hologram it casts on the ground, and pressing . Healing uses an amount of Sparklium that scales up with how much health is going to be recovered, however, with being used to restore a quarter of a leader's health. The Sparklium Saver may be used to reduce the Sparklium used by half, rounded down, to.
 * Sparklium Extractor: Doubles the amount of Sparklium obtained from any resource that is brought to the Lander. This includes, but isn't limited to, fruits, treasures, and of course, Sparklium seeds.
 * Sparklium Saver: Reduces the amount of Sparklium the Lander uses for any task by at least half of the original cost.
 * Jet Juicer: Increases the juice obtained by all fruits by 10%. The juice used for sprays obtained from Burgeoning Spiderwort berries is also increased by the same amount.
 * Revitalizer: When a downed leader is brought to the Dolphin Lander, the Lander will ask the player if they would like to spend to revive them. If the player accepts, the Lander will beam up the downed leader, revive them, and beaming them back down. Revived leaders only have a quarter of their health but they can be healed. If not, the Lander will simply beam up the downed leader and keep them safe for the rest of the day. The player can also change their mind and revive them after initially declining by interacting with the Dolphin Lander's hologram and selecting the option to revive the downed leader.
