Help with a "bonus acquired" sound effect

Hi,

I’m a programmer and I’m clueless when it comes to engineering sound fx for my game.

I need a sound effect for when the player kills a highlighted enemy. Imagine there are five of the same type of enemy on screen and if you kill the highlighted one you get some bonus points. Kinda like a 1-up sound but maybe a bit mellower.

Does anyone have anything like this…or know how to make it?

Thanks
