Dwarf Toad
Lowland Dwarf Toads are practically impossible to spot because they hide in bushes, they are very camouflaged, and they are miniscule. They grow up to one inch (2.5cm) long. As tadpoles they are less than one centimeter long and stay in a small hole so they don't get eaten.

Why do you miscategorize your post with an "adventure" tag? It has nothing to do with what you write.
I mentioned searching for them and them being hard to find. But you’re right it’s a stretch to tag it as adventure.

Ooooooooh, SO CUTE! Well worth the adventure of hunting for this little one - assuming that this is your original photo?
