can't remember where I found it, maybe here in freestuff-- 'Aurora' headmorph for AikoLE. When applied it gives Aiko Vicky's head, which is great for more realistic images of her.

There are/were magnets available to give the various gals fuller chests  _look for willdial's sets (depends on taste of course). The nice thing about magnets is you can usually apply them to clothing too, whereas morphs don't often translate that way in my experience. A note about the magnets- you can select the magnet itself after applied and scale it to fit your needs.

Hairs- definitely all from Kozaburo and maya, and keep in mind any hair prop (not conforming figure) can be scaled to fit any figure with a little dial moving. The standard hair for Wapicodoll is great for example. Aiko also comes with a nice hairprop.

Figures- you have Daz incl Aiko and the animals from their free site- gorilla, sanke, python. Contentparadise puts out a new critter each week it seems, though with poser 5 downloading may have to wait.  Mayadoll and Sara as mentioned. Sixus1 poserfreebies.com has an assortment of figures too, several that give unique options- Behemoth is a big fella, and Britta is a child. Some cool monsters there too
