Louie
His first appearence is in Pikmin 2 and he serves as a partner to Captain Olimar in commanding Pikmin as his sidekick. Hocotate Freight runs into financial trouble after Louie, a new employee, was shipping a supply of the very valuable Golden Pikpik Carrots, was apparently attacked by a ravenous space bunny who is said to have devoured the entire cargo of carrots. The President took out a giant loan to cover the losses of the carrots, and has no way to repay the loan. After the return of Olimar, the President instructs Olimar and Louie to head back to the Pikmin planet to search for treasure and save the company.
After Olimar and Louie get the entire 10,000 Pokos worth of treasure, Olimar returns to Hocotate, only to find he forgot Louie. Olimar and the President of Hocotate Freight return to the planet to find him. Louie wanders around the planet aimlessly and hopelessly for a bit, as seen in the credit roll of the game. Olimar and the President later find him hidden deep in the Dream Den with a Titan Dweevil. They rescue him and send him to the ship's treasure hoard, since the ship used for travel is already full, calling him the King Of Bugs.
It is often of constant debate if Louie was a captive of the Titan Dweevil, or in actuality controlling him. E-mails the player recieves from Louie's grandmother reflect that Louie always loved bugs as a child, so this theory is almost very feasible.
He is actually the one responsible for the debt Hocotate Freight suffers, not a "ravenous space bunny" like he lead you to belive at the start; as it was truly he who ate the load of Golden Pikpik Carrots.
