Armadillo, for instance, from The Garden State needs no introduction (8)
I believe the answer is:
edentate
'armadillo for instance' is the definition.
I can't tell whether this defines the answer.
'the garden state needs no introduction' is the wordplay.
'the garden' becomes 'eden' (I've seen this before).
'state needs no introduction' becomes 'tate' (I can't explain this - if you can you should believe this answer much more).
'eden'+'tate'='EDENTATE'
'from' is the link.
Can you help me to learn more?
(Other definitions for edentate that I've seen before include "Sloth, perhaps" , "Gummy" , "Toothless creature" , "Animal as sloth, armadillo" , "teeth? None" .)
