Exemplification of 'being not idiomatic'

apple: a round fruit with firm, white flesh and a green, red, or yellow skin.

If I use ‘apple’ as ‘a round fruit with firm, white animal flesh and a green, red, or yellow animal skin,’ is it grammatically and semantically right at least in imagination but not idiomatic?

I wonder because I want to use anthropomorphism, and it needs not only to be like animals, but also to be an animal, so I want to use this word in a unusual sense.
