Does a frog have Buddha nature?

Forgive me for straying a little (a lot?) off topic, but I wanted to share a small something with you. Coming home one recent evening, we found a visitor on our doorstep. It seemed that our usual doorstep resident, the garden Buddha, had acquired a little student. A frog had taken up a meditational pose alongside him and was evidently lost in deep contemplation, so much so that he was oblivious to our shuffling past him to enter the house, put on the lights etc.

There is a Zen koan which asks, “Does a dog have Buddha nature?”, the answer to which is considered inaccessible and elusive. Adjusting this koan slightly, however, I think that we may have found a valid response – a frog most certainly does!
