Frog in the greenhouse

A frog has been living in our greenhouse for several weeks now.  Normally he or she just keeps themselves to themselves (usually inside one of the grow bags) and I occasionally see its face when I am in to do a bit of watering or to ring my mum.  However, when thechimp slopped in the greenhouse in his slippers with the watering can today, it really disturbed the frog and it hopped about all over the place.
