Skippy
This is the first project where I actually made modifications to the sounds a device creates. But let’s take a look at the toy, first.
Unfortounately I forgot to take pictures when first opening it, so these already show it with my modifications.
It had a small loop at the bottom that attached it to a plastic ring, to which other, non-noisemaking toys were attached. Each of those buttons triggers different sounds, which seem to rely on a shared, internal counter.
