In a similar, but more entertaining, vein
.. my mum lives in a big house seperated into flats. One of the neighbours put in a fishpond against the wishes of the neighbours and, more importantly, my mum.
I told my mum what I was going to do, but she wouldn’t let me so when she went on holiday, I did it anyway.
Visit toy shop, buy a party pack of mixed balloons
Visit charity shop, buy some baby clothes, wools best beacuse it absorbs water and gets heavy
Inflate enough of the right balloons and tie them together in a “head, body, two arms, two legs” configuration
Squeeze them into the clothes
Plant the result in the pond
Pond was filled in shortly afterward.
