This new plane is perhaps the more exiting of the new cosmology. I think it can be used for a lot of heroic adventures, and that those adventures may be somewhat different of the average, because the monsters won't be the great classic (undead, dragons, fiends and humanoids...) of d&d.
so, I would like to compile a list of the monsters that are crying out loud "use me in a feywild adventure !"
I will start with the 3.5 MM :
* Hags : all variety, including night hags, who have the power to enter the prime at night...
* Fey : all variety, of course, with evil or savage variants
* Giant eagle and giant owl : intelligent beast seems perfectly appropriate.
* Dire animals : they should be different of their prime relative. How ? They should always be the pets of someone... Formorians ?
* Aranea : everything shapechanging does fit well in this plane. Oh, and, because there isn't ethereal plane anymore, maybe she can kill the phase spider and take its stuff... An aranea with the ability to planeshift and shapechange would be nice
* Barghest : Here is what happen when a breed of demons enter the Feywild.
* Centaurs : probably, but I never knew what kind of adventure do with those guys...
* Cockatrix : this kind of magical beast (puny looking but really dangerous) has its place here.
* Dragons : some of them could have retreated here, to escape older rivals. So, while wyrmlings are too young for the place, and Great wyrm to powerfull, adults and young adults seems good candidates
* dryad : see "fey"
* eladrins : looks like they came from this place
* ettins : the two-headed talking brute fits perfectly IMHO in this kind of setting
* will o wisp : of course ! However, this one may also live in the shadowfell. I wonder if there are passages between those two planes ?
* gargoyle : maybe. Another "what to do with this monster" however.
* giants : the land of giants seems a very close concept to the land of fey. And, if the formorians are giants...
* gnomes : Yup ! They are not in the PHB because they are hidden in the feywild.
* griffons, hippogrifs... : the classical mount of the nobles in the feywild
* merfolk : probably. They may have hidden cities in the feywild, where prime humans don't see anything but the sea.
* assassin vines and other plant creatures : yup. This is the place where the forrest can eat you.
* lilend : probably, they are native of the plane.
* winter wolf : yup ! The hunting beast of the frost evil faeries...
* were-stuff : I guess there should be a difference between the one in the feywild, and those living in the prime. I think those living in the feywild are somewhat more in control of their curse, and can be of any alignment.
* ogre-mage, ogre : see giants. They should be more intelligent (ogre) than their mundane counterpart. Think Lyonesse ogres.
* roc : giant bird are cool, especialy when they eat the PC horses.
* satyrs : of course, yes.
* sphinx : answer the riddle or be eaten. This kind of interaction is somewhat easier to acknowledge in the feywild.
* treant : not all of them are good...
* trolls : see giants
* worgs : see winter-wolf and giant eagle : talking evil beasts is a classic concept.
