The Phantasmal Poision Frog

As it is now, the Phantsmal frog is a tiny frog, only 1-4cm long. With the humidity of the amzaon changing, it needs a way to deal with the percipitation deficit. As it exists. itś skin is suited for absorbing humidity through the air. Unfortunatly, in the future this may not be an option. A way to deal with this is to develope thicker skin to prevent water loss. Another way for it to deal with less humidity is the change to itś feet. The toes will slim down to be better suited for gripping non-slick surfaces. this has the added bonus of more dexterity. the final hypothetical change is to become overall chonkier to once again, help prevent water loss through itś skin.
