Interesting carvings

I found these small lovely carvings on the tall fences around an open car-park in Sheung Shui.

These carvings might have been made from moulds. I did not know what materials were used, but the figures on the carvings interested me most.

The characteristics of these carvings are that they are artistic in some ways, cartoon-like and bring life to the fences.

Here is my observation:
[1] The top design is a funny bunny riding on two small kittens.
[2] The middle one is obvious enough. There are two fishes linked together, fin to fin and tail to tail.
[3] The bottom one shows two rabbits standing on a large butterfly.
Do you agree with my observation? If not, what is yours?
