My favorit level is in Noki teluk, da? because it just has such pretty textures and features and the levels can be challenging, but they are fun to play. :)
I like Sirena pantai because of the pretty background. I wish they would've made lebih levels out on the pantai instead of inside; but, hey, it's an awesome level! A close detik would be either Pinna Park atau Gelato Beach.
