John, I'm Here to help you with your project! Please, accept me!
Rodney posted some characters we miss from older versions of A:M
I think Sally would make a prefect doll, Spikey's eyes "with the eyebrows" would be useful for your charaters "please, use them (you are also free to modify the eyes the way you want)" and the characters you must use are "Galoop, Critter, Spikey, Flim Flam, Sally, Gurgle Glug, Billy, Ted, Professor, Tea Lady, Prinsess, Gent".
Now, he also posted some A:M EXTRAS characters: http://www.hash.com/amtutes/X_Vol001/Menu/
Please, use "Mika in a Dress, Chameleon, Howie, Mick, Ricky Rat ,Neutron and Female B".
I think Buzz, Marvin the Martian, the Skeleton, Gnome, Thom, Gala, Ms. Goodbody , Rabbit (2002 version), Wookie, Kee Kat, Old Man, the Alien with the blue shirt and Eddie "in my opinion" can't make very perfect toys "for your project". You can re-rig the old ones and all of them with the 2008 rig "if you want, please.I realy want to see them (the 1998 characters) back in action, because they're my favourite models ever! Anyway, Eggiton posted some more models on their website and I downloaded some for you.
Please, use them!
5 cars (I think)
And an older rabbit version that would make a better plush toy "in my opinion".
WARNING. YOU MUST ALSO GIVE TYPES OF TOYS AND FEELINGS TO EACH MODEL:
Fish (from 1999): Plastic
Flim Flam: Plush
Gurgle Glug: Plush
Tea Lady: Plush
Mika in a dress: Figma
Ricky Rat: Robotic (press his arm and he will move)
Female B: Plastic
Yetti: Robotic (press his arm and he will move)
Red Robot: Metal
Little Furry guy: Plush
"CartoonRabbit1.mdl" : Plush
Cartoon Elephant: Plastic
Cars (all of them): Plastic (with moving tires)
Hope I helped! Anyway, I hope you will like the models.
