"The Black Rain Frog: A Bizarre, Grumpy-Faced Amphibian with Limited Jumping and Swimming Abilities"

The black rain frog, known for its grumpy face, is a fascinating amphibian found in the forested slopes of South Africa. Unlike most frogs, they are terrible at swimming and jumping but excel at burrowing. They create intricate underground systems where females lay their eggs, and their tadpole stage takes place underground. Above ground, they run or walk instead of hopping and have the ability to inflate their bodies as a defense mechanism. These frogs also produce a slightly toxic milky substance. Despite their grumpy appearance, they are considered cute and unique due to their distinctive features and behaviors.
