All-knowing hobo

One of the poor inhabitants of the Slums. He can be found south from the Don's Lair, near the large rock (he would be to the left from it).

When approached, he demands something to eat. He can accept any of the following:
 * Apple
 * Big Fish
 * Fish
 * Seaweed
 * Small Fish
 * He wouldn't accept the Weird Fish, despite the option to give it being available; even he's not that hungry!

Once provided with food, he always says some random tip. Known advices include:
 * Apple trees in the Forest Park, and that they can occasionally produce the rare Golden Apple.
 * The secret phrase you need to tell to the Devil's Drink's owner to "make some money". Unlocks the option to tell bartender the secret phrase.
 * Where to buy fake UNA passes. Unlocks the option to buy fake passes from "junk seller" on the Black Market.
 * Secret meadow in the forest, and its relation to the Fairy Dust.
 * The Bathhouse provides special services.

He only says one tip per day (he would repeat the last tip he said when approached), so in order to hear something else you need to rest first (fortunately, you can do so in the same location).
