In Indonesian folklore, there exists an interesting tale of black magic practitioners who can shape-shift into a boar. The practitioner needs only to wear a magical robe to turn into a large boar known as babi ngepet. The goal of such transformation is often theft.
In this animal guise, he enters the targeted house in stealth and rubs his porcine body against every nook and cranny of the dwelling, and quickly retreats. Once within the confines of his own place, he reverts to human form, his magical robe now laden with money and precious loot from the targeted household.
