Why not a solenoid.
It does not appear the the mouth moves that much, so you could use a solenoid. It will be quick of course. I have machines that have 24 volt solenoids that pull about 1/2 inch. Just pulse when you want mouth to open. Oh and solenoid are plenty strong. The ones on the machines pull down spring loaded rollers. The applied pressure on the rollers exceeds 20 lbs of force.
