The Devil's Gift (1984) 
A young boy gets more than he bargained for one birthday when he is bought a cymbal playing monkey toy which just happens to have been possessed by a malicious demon.
The monkey-bound demon then sets about attempting to kill off the family one by one through a series of gradually escalating psycho-kinetic and possession based events.
Whilst The Devil's Gift doesn't really bring anything new or original, it is for the most part competently made and adequately paced. However, aside from the gimmick of the creepy evil monkey the film is a little bland and predictable and certainly nothing you won't have seen before in some form or another.
