It is difficult to get enough food in the beginning. You need to harvest every tree you come to, pet and nibble every pig, squeeze every chicken and milk every butterfly.
SPOILER ALERT!
You can go into the Ancestral Lands: Baqala, Choru, Xalanga and Zhambu. These are in the North. There is a Timer on these but you can win a Badge or two while there. In these lands, you will collect coins for Currants, Mood, Energy, Faster Learning, Giants Favor. You may also receive High Energy Foods, Gems and a lot of Paper. Beware of the Jujus! Jujus will steal from you. I go there for the high energy foods, the coins and the Gems. It can be very profitable. When the Timer runs out, you will be evicted to another location.
Always remember - You can sell things to the Vendors to get more Currants with which to buy Food, Drinks and other items.
Someone gave me a couple of grilled cheese. :3 But, how do you get to the Ancestral Lands. I remember doing something that involved collecting 30 coins...
Look in the Northern regions of the map. Anything that looks savannah-like is most like the ancestral lands. Baqala, Choru, Xalanga, Zhambu. You can take the subway to Kongu Hop in Andra, or Pitika Parse in Kajuu and walk from there.
I wonder how that went? the op is still at level 5 and hasn't been back since the post. She's still learning skills, maybe she'll be back later with more skills.
