Halloween // I need help finding a picture of a Specific Halloween costume

In third grade I went as Frankenstein for Halloween and my costume was made from multiple different things but one part of it was from an actual Frankenstein/Zombie Halloween costume that had an open chest displaying ribs and the heart (it's possible it was just the heart but I'm pretty sure the ribs were visible too) and it had a air pump that went through the sleeve and had a little heart on the end that when squeezed made the heart in the chest beat. I long since got rid of it but I want to find a picture of the costume that the chest piece came from but I can't find it anywhere. does anyone know what costume I'm talking about and where I can at least get a picture of it?
