LBP n00b requires assistance. :D

Hey guys. I'm just wondering something which may (or may not) be completely elementary..

I've done the garden king story levels, and when I finished those, he told me I should go to to the savannah to meet another dude. I can't find this savannah anywhere. Help? Where do I go from those three or four garden levels?

I havent done much after the King's Tie minigame and I dont think you can-- It's a beta so it's most likely locked so you have to buy the full game.
