Olimar's son

Olimar's son is introduced in Pikmin 1 in the log book, along with the rest of the family, including their dog Bulbie, and in Pikmin 2's space e-mails. It seems that he wants to visit the Planet of the Pikmin, and was upset that his father went back to the planet a second time without him. His e-mails imply that he really admires his father's being a Space Captain.
