Capricorn - that includes personality! (3,4)

I believe the answer is:

the goat

'capricorn' is the definition.
(I've seen this in another clue)

'that includes personality' is the wordplay.
'includes' indicates putting letters inside.
'personality' becomes 'ego' (I've seen this before).
'that' going around 'ego' is 'THE GOAT'.

I've seen this clue in the Sydney Morning Herald.
