I rate my voice assistants by the quality of their "animal of the day"-- by this metric, Google Home is the clear winner. It's hard to even get Alexa to play you an animal sound, while Google has a really thoughtful Animal of the Day feature with sounds and animals facts.
My toddler listens to the animal of the day at least once a day on it, comprising >50% of my overall voice assistant usage, and I love to hope that I'm a weird outlier on some confused analyst's usage dashboard.
My toddler also loves this feature. Can confirm animal (and rocket/train/baby) sounds make up a significant portion of voice assist in my house as well.
Fun fact, if you Google voice search animal sounds on a pixel, chrome will (most of the time) serve up a whole animal sounds dashboard with pixel art.
The toddlers love yelling at it and getting it to play songs they like. The older ones, well, I guess do the same thing but with different songs, and occasionally Wikipedia-style quick answers.
