Halloween Animatronics pop out

So for Halloween I want to make a pop out/ fly out creature. I want it to sit tucked away in the corner then shoot out two to five feet towards unsuspecting guests, to give the illusion of something flying out at you. I was thinking of doing the scissor (http://www.frightprops.com/pneumatics/kits/animatronic-kits/horizontal-scissor-mech.html?SID=d3f43bbaffe0a34f01e47e75eade4e39) but need to figure out how I'm going to be able to make it repeat over and over without having to reset it constantly. If you have any ideas please email me.?
