I don't know if anyone has already asked this, but are the new plants and bugs only in the new world? Or can you find some of them in the two original towns?
The plants and insects of GF can only be found in GF. But your sims can take them home, and display them there. The GF plants can be planted in your sim's garden, but only after they have identify the plants.
