Sound clips from the 1st Ghostbusters Movie

I’m new here and I desperately need help with a project that I’m working on.I built the Ghostbusters HQ from a Lego set,I’m adding lights and now sound to it.I’m going to have the Ghostbusters theme in the background but I want to add some more sounds from the movie but I’m having trouble finding what I need.The first sound I need is "We got one"with the bell ringing,video arcade sound with donkey kong and centipede and some slimer sounds(I like slimer from from the real ghostbusters cartoon series)and a fourth sound that I haven’t decided on yet(any suggestions would be appreciated).Thanks for any help that anybody can give me

For the fourth sound, I’d propose the Containment Unit alarm.

I like that idea for the fourth sound.I’m hoping there will be someone here on the forum who can help me with the sounds.
