I'm sure he managed to jump out. We had a toad in ours shortly after installing it and he got out (I hadn't seen a toad in a pond before but I presume they also like an occasional swim).
We don't have any water around us for a couple blocks so I have no idea where he came from. I also have no idea what he's eating but seems happy. I managed to get a little better picture of him yesterday but I'm still waiting for the lily pads photo op.
I keep saying "he" - no idea is it's a boy or girl. I don't want to scare him/her off for information that really doesn't matter.
