The Main Engine of the Dolphin's is only part found on the first day in Pikmin, so that Captain Olimar is able at least to lift off from the crash site to escape the planet's nocturnal beasts. He was able to transport this part with the help of the Pikmin he discovered upon landing on the Pikmin Planet. With the main engine restored to the S.S. Dolphin, Olimar is able to continue on to The Forest of Hope in his continuing quest to find the 30 lost ship parts. In Pikmin 2, the Dream Den replaces this part's location.
Collecting the PartEdit
On the first day you go through the main tutorial about the Pikmin. Once you get the first Pikmin start collecting all the Pellets including the ones on the two small stumps. Once you have 10 or more Pikmin, command them to move the box. Once the box is out of the way you find the engine. Don't think about grabbing it yet. Head up the rocks where the box made a ramp and get all of those Pellets until you have 25. Now you can pick up the most important part of the S.S. Dolphin.
