Well if they're here they can't be called that as thos nammes are all copyright so I'd suggest a search of freestuff with the words 3D  character and see what comes up...they might be there as "alien" or something....all I can think of.. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
