A South African family walking their dog in a forest captured an unbelievable video of an alien-looking frog emitting a simply astonishing sound.
The puffy amphibian was spotted by Simon van Nierop's dog as his family explored the Tokai Forest in Cape Town.
When they approached the unique creature, it revealed a defense mechanism worthy of its uncanny appearance by belting out a blood-curdling scream.
No doubt quite perturbed by its unwanted admirers, the frog continues its haunting wail until the van Nietrop family leaves it alone and seemingly moves on to torment some other denizen of the forest.
