What's that smell? Holiday fun has been causing quite a stink at Battersea Park Children's Zoo.
On the poo trail, which finished this week, children looked at the size and shape of different droppings, and matched them to the animals who made them.
Lemurs, mere cats, pigs and mice were among the creatures whose poo got examined in the pongy task.
Organiser Fiona Vella said: "Kids love toilet humour so they really enjoyed it.
"I had to replace a couple of the droppings, but the pig poo preserved quite well."
