The Bundimun has some rather strange abilities. It tends to crawl under the floorboards and behind walls in houses, and it has the ability to rot the house construction out from this. The Bundimun was able to create a weird substance from itself which was extremely acidic. It is this substance which is able to rot houses, and it can also be used in different potions and cleaning products. As an example, it is used in the Doxycide. It might also spit this acid out when annoyed.
Now this is a creature which is interesting. It is not an unlikely pet to hold, and many witches and wizards might actually already be holding this creature as a pet without them knowing. But, if you willingly wish to hold this creature, it is understandable why! It might even be the perfect pet for a Potioneer, who wishes for a creature that does not require much work to hold. Of course, it is highly suggested that whoever holds this creature does not live within a house with a tree structure, unless the owner constantly keeps an eye on the pest, ensuring that it does not get into the actual tree structure unless they wish for a new place to stay in the end. Either way, the Bundimun is a rather low-maintenance creature, which does not require much from its owner, so it is perfect for the one who does not wish for too much responsibility.
