Rare encounter on the tractor tour

The tractor swung past a small rainforest patch we'd put in 2 years earlier; checking on the trees, growth rates, weed infestations. A blue flash from the black apple, a tree I remember planting. The dearest little frog not much more than inch in length. And it was turquoise. There aren't any blue frogs in Australia. Who are you my dear little friend? And where have you come from? And your brassy legs. What a vision. Some say it's probably 'litoria fallax', but I'm more inclined to say "litoria tractoria'. Just have to paint the tractor blue.
