Inspirations: batini and baterror are based on the manananggal (i am 99% sure i spelled that wrong), a mythical creature from filipino myths thats basicly a vampire with no legs Snaplant, Chwamp and Crocodepths are based on Venus Flytraps and crocodiles And Charbuncle is based on Will-o-wisps and the carbuncle (a mythical creature from south american folklore that is described as a cat sized mammal with a glowing gem on its forehead and an armadillo shell)
If you add the snaplant line into the game, it has to be found in a swamp area And you find Charbuncle & Batini in caves (charbuncle is extremly rare though)
