The Pinwheel Clause- If an area has two or more parts (like Pinwheel Forest inner and outer) you may catch a pokemon in each area IF the areas have different catch lists.

Pinwheel is one example, having Tympole and Timburr on the outsidearea, while an assortment of BUg types in the Inside area.

Other examples include; Safari Zones, Virbank Complex etc.
