When they breed.
The hippos have bred. 
I went a bit nutty and made anfew of them. Three I sewed by hand and two I made by machine. The ones made by hand are the better ones, the shape worked better.
Meanwhile the tadpoles are pretty much gone. The pool changed colour overnight. 
Cassandra got in two days latter and collected some of the leaves down the bottom. The filter is working overtime. We did find a couple of live ones, thankfully I didnt drink it.
Wow. The pool colour is so much better. A lovely blue….
You are starting your own zoo with those hippos
