Cetus Quest

In order to do the Cetus Quest, you need access to P1.

First, you must buy the Extinct Animals Book and Tablet (if you haven't already) at the Garnesto Shopping Mall. Read the book and go to the Spaceship Hangar to talk. Go to the shopping mall, buy 10 pieces of wood, an anchor, oars, and a lot of bait (7-10 pieces). Go to P1 and go to the Coastal Waters area. The text 'Use Boat to Sail Closer to Fin' will be there; click it. There will be a few pages and links chasing the fin, eventually it will give you the option to throw bait. If you are successful, you will be brought to a new page and given a Cetus egg. If not, repeat until you do.
