Among the living creatures seen in Dracula’s castle in Transylvania are opossums, armadillos, and an insect known as a Jerusalem cricket (Stenopalmatus Fuscus).
The Jerusalem cricket was common in Southern California, which may explain its cameo in the film.
The inclusion of armadillos was due to the fact that armadillos had occasionally been seen digging in graveyards, which led to the mistaken belief that they would dig their way into coffins and eat the cadavers.
