Beep! Beep! looked like a good primer:
It's got all the vehicles - cars, lorries, steam trains humanely transporting circus elephants in special padded carriages etc. etc.
Now, as a parent, I expected it would be some years before my daughter was learning about stuff I didn't know. But on page five of Beep! Beep! what should I be confronted by but an owl driving a steamroller:
I thought I knew quite a lot about owls - they have exceptionally rotational heads, they sometimes have tufts, they only go either 'too wit' OR 'too woo', NOT BOTH* - but I had literally no idea they sometimes drive steamrollers.
Of course, now I think about it, it makes a lot of sense. It's easy to imagine an owl crashing silently through a forest at night on enormous iron wheels as silent as two dandelion spores colliding, manic, silent cackles echoing silently round the cab, before parking silently in a barn and silently scraping crushed mammal carcasses from the merciless metal cylinders of silent death with its beak and tongue.
I don't know why I hadn't thought of it before, to be honest, I mean, look, its skeleton is perfectly adapted to such behaviour:
I wonder what that owl is thinking?
*If you hear 'too wit, too woo' that is TWO OWLS.
