The Namaqua Rain Frog (Breviceps namaquensis) is able to puff up its body to intimidate predators, but its call is less intimidating than adorable. In its inflated, agitated state, a passing dog might mistake it for a squeaky toy.

Dean Boshoff recorded this video of the puffed up frog on the sand dunes near Port Nolloth in Northern Cape, South Africa.
