This summer we have had geckos in the greenhouse (they have their own special access so they can get in and out) and every now and then I have discovered a treefrog hidden away, but now we have something new. This is Tweety Pie. Not sure what he is, but he has been roosting in the greenhouse for the last week. I shut the doors after dusk, after making sure he is in there and then I let him out in the mornings.
