How can you obtain more bottles?

This is really bugging me now!! I just need one more really. But any advice would be greatly appreciated.

Thankyou
Rossko.

Explore lots. Answer to everything.

The four bottles in TWW
Medli give you one
You get one from a sub near Bomb Island
The next is for sale on the Shop ship at Rock Spire Island
The last you get by following Millie around the town after you resuce her, make shore she doesn't see you by hidding behind walls. Eventually she goes to Zunari's shop and the safe there. Sneak up behind her and respond with the top answer for ever question. She gives you a bottle and then leaves.

This should be in the official windwaker help thread.
