Sniffers have no egg laying sound, despite laying them like Chickens

The Bug:

When breeding two Sniffers, instead of spawning a Snifflet, one of them plops out a Sniffer Egg item onto the ground. This is similar to how the chicken egg laying mechanic works, where the Chicken plops an item onto the ground.

However, unlike Chickens, Sniffers don't use the egg laying "plop" sound that communicates that an egg was dropped.

This behavior can be observed here:

Steps to Reproduce:

1. Observe how when a chicken lays an egg, it plays a "pop" sound

2. When a Sniffer lays an egg after breeding however, observe how no sound is played at all
