'she' is the definition.

'a perfect ending to little rudolph' is the wordplay.
'ending' says to take the final letters (the letter at the end of the word).
'to little rudolph' becomes 'rudy' (I am not sure about this - if you are sure you should believe this answer much more).
The final letter of 'perfect' is 't'.
't'+'rudy'='TRUDY'

'brings' acts as a link.
