Before leaving for Choco, search the area approximately five
spaces right and seven to nine spaces up from Quintenix. Starting
from Quintenix, fly to the right just past the first yellow star.
Then, fly upwards until reaching an area with a small blue star
to the left and a large yellow star to the right. The planet Kirara
is located between those stars. The library on Kirara contains
the complete Inventor's Friend collection.
