These creatures live in the Amazon rainforest.
They have razor sharp teeth and an organ in its throat which creates fire to burn the food they eat so they can eat almost anything.
They can change their bodies' shape and can turn into any animal, bird, insect and even a human.
But every creature has a weakness this creature too has a very funny weakness. It hates apples. So if someone manages to throw an apple in a Vamkinggan's mouth it dies.
