Spawn
My frisky frogs have brought about the most exciting thing to happen in the pond since the baby fish 18 months ago: two great lumps of spawn (the smaller one is pictured).

The frogs were introduced to the pond as spawn themselves two years ago. Disappointingly there was no spawn last year. Meanwhile, there can be no doubt there are no longer any fish in the pond, and while I will reintroduce fish later this year, I shall be waiting until the tadpoles can leave the pond under their own steam.
