Captain Olimar's Journal
"The ship has a lot of self-importance for a machine. Apparently, machines can exhibit human characteristics after all. Perhaps they even have a soul? If this is true, then maybe you can work them into the ground until their spirit is broken and they stop giving you the lip...Oh no...I'm turning into the President!"

"According to my measurements, almost no energy should remain within... yet some does. The energy one can draw from matter has a limit, but the energy of the heart is endless. Perhaps that is the case here. This proves that machines have will and determination!"
