The main goal in the game is to retrieve ship parts by using the three varieties of Pikmin available in different combinations. Captain Olimar discovers multi-colored plant-animal hybrids that willingly follow his orders and help him recover the parts. All three of the Pikmin colors that Olimar discovers must be used in order to overcome various obstacles and complete the game. The Pikmin creatures come in three colors, including red, yellow and blue. Red Pikmin are the first type found in the game, and more powerful than the other two varieties and resistant to fire. Yellow Pikmin can be thrown higher than the other two, can carry explosives called "bomb rocks", and also excel at trivia (as read in Captain Olimar's Log on the 17th night). They are utilized in various tasks, including carrying objects and enemies, breaking down walls, and defeating enemies. Blue Pikmin are the only ones that are able to survive in water. Objects that can be carried vary between ship parts, enemy bodies and pellets. Only one hundred Pikmin can be on the ground at a time.
