This is a quite small island, so unlike for others islands, I wont leave many comments here, just the picture of the style and flower location in the order you should (probably) find them. Additionally, no pictures about book table locations for this island:

First Style

Second Style

Third Style

Fourth Style

Fifth Style

You need to cross a gap on the wall as a bridge isnt lowered. You could go down at the middle of the gap and so you could eventually reach this flower.

Thanks a lot!

I have some improvements for the instructions about O' Higgins Village Condominiums.

After the 1st style when you take the seed for the first time don't use the elevator. Turn right isntead and open the "door" to get a book and a style. That's why this picture with a words "You coming from here" should be moved a little bit up.

And some words about the 3rd book. It's Ok to put the seed into the transport machine, because in a minute you can lower the bridge, take the seed and go back to the "door".

So if you hear the belugs pass, then the squid is already gone around 30 seconds and it takes around 4 minutes for the squid to come back XDDD
Miss K Jul 25 @ 10:33am 
If someone struggles with the giant squid:

Go to the spot on the guide next to the broken bridge pieces where giant squid path and beluga path meet. Face "outwards" towards the open ocean. On the left side of the screen you must see the 2nd "feet of the bridge/street. Stay close to the outer swimmming boxes. A broken street bit is right behind you.

Look down to the water. Listen to the soundscape!!!! The squid pushes through the wather wooosh wooosh and makes sounds like long deep creaking of wood! X'D.

Look at your character. She stands up and climbs to the front of the boat when the squid passes.

@joridiculous: YW, but relic on O'higgins? On islands there are only styles, books and flowers. Relics are the green gears on the map.
