SOOO CLOSE!! (Also, HELP!!... Sound effects?)

Ok, I know I haven't been on here in but I told y'all it was gonna happen, so yeah... Don't hate me...

Anyhoo, I have been working on this animation and I am SOOO CLOSE to being done, but I have run into a speed bump...

You know that sound the characters make when they get surprised?
That kinda springish sound?
The one that Pinkie Pie makes in the first episode when she sees Twilight Sparkle for the first time, right before she jumps into the air and gasps?
This one?: www.youtube.com/watch?v=Eq2MTJ…

Well, yeah... I CAN'T FIND IT ANYWHERE!!... ANYWHEHEHEHERE!!...

HOW CAN I POSSIBLY FINISH MY LATEST CREATION IF I CAN'T FIND IT?!


And so, I come to you, upon my knees from which you will find no arrows protruding:
Does anypony on earth (or equestria) know where I could get this sound effect?!
You guys are amazing, so I know somepony is smarter at searching than me! (Doesn't take much...)

So yeah, please help. I will forever love you!!

Oh yeah, here's a screen cap: blackgryph0n.deviantart.com/ar…

LOVE Y'ALL!!

EDIT: Thanks for all your suggestions everypony! Y'all are !
I was able to create the SF on my own and it sounds pretty dern close!!
Now that y'all know that though, I'll bet you will scrutinise the crap out of it...
Thanks for everything guys!!!
