Walkthrough

Get out of bed and examine the right side of the closet for 6 Drawer Things, then examine the spear stand for 2 Strategy Books and a Prodigy Notebook. Talk to Gunso a bunch of times for a Gunso's ??? item, as usual. Now go out of the house (it's Donfan's, in case you hadn't noticed). Talk to Bikkebakke above you, and you can fish for an octopus. O_o Hit left, down, and right continuously (i.e. LDRLDR etc.), then when Bikkebakke prompts you, hit A a bunch of times to reel it in. After the scene, talk to the octopus to get a Bastard Sword and Aurora. Now head inside the top left house; examine the table for 3 Sweet Wines and 2 Super Vodkas. Examine the right side of the closet for 3 Drawer Things. Bikkebakke's mushroom shop and the weapon/armor/item salesman are at the lower left along with the dragons. You know the drill, equip, buy, feed, then talk to Sendak to leave. At this point I had all dragons with Fire at 100, so if I ever got any more Flame Grass I just sold it (it's good money!).

This one's pretty straightforward; you'll have to smash your way through more or less all the enemies before reaching the boss. Have dragons on "Come!" to help you out. They should get rid of the ladies quickly; the Colossuses (Colossae?) are one-trick ponies; they're strong with a lot of HP, but they're not hard. Have your dragons take care of the Tentacles and work your way up to the boss, who's pretty much a pushover.

After the battle, head up into the door. From now on, Yoyo and Sendak can summon Leviathan!
