Hoho!!! I think you're ready for a new adventure, sonny! I've just finished a little gift for yah - she's small, but shes got spirit! I daresay she should help yah get around the other Islands!
The islands of APICO are split into different biomes, each one having it's own unique elements, Bees, Flowers, and Climate.
At the beginning of the game you start in Port APICO, which is located in the forest islands. As you progress through the game and discovery enough bees you'll unlock the Boat (bought from Skipper) which lets you travel across water to the other islands.
