Thanks for your feedback... pleased you like the sound. To answer your question I decided to make a pig because it's something different that I hadn't made before and there aren't many on Thingiverse... then decided how I wanted it to move... because I like making moving things... and having decided to make a head / face there was the possibility of it making a suitable sound as well. All of this was worked out in my head prior to starting... then you just design to your idea... and I'm pleased with the result. Yes the little outsets were always in mind to ensure some friction between the spring and outer surface.
All the best
