That's a pretty color for a frog.I have it in some Christian pocket cards I bought a long time ago. They say: Fully Rely On God(FROG). They have 2-3 different colors of frogs, 1 of which is ROYAL BLUE like the one in the puzzle.
Usually brightly colored frogs are poisonous - at least the ones from the Amazon area. Quite a few animals are brightly colored as a warning to potential predators that the animal is poisonous - but some, will kind of mimic a poisonous animal to avoid predators.
For example, the Monarch Butterfly is toxic to many animals, but the Viceroy Butterfly, which looks a lot like the Monarch are not toxic, but many predators will avoid them.
