Refrigerator Pig and other vintage electronic animal noises

OK, here is schematic of old Radio Shack fridge pig (with photocell):

Now it sounds the shitz but I like it because it's fun.
Does anyone have links to other animal noises done using vintage
electronics (meaning op-amps and inductors etc)?
When I google I find lots of birds but not much else.
