An intensified taboo marker, consisting of two or three crossed arrow-grass canes, pūdung.
The symbol is made of arrow-grass canes, bilāu, tied at the top. A single arrow-grass cane, pūdung, does not have the intensity of two or three crossed arrow-grass canes. This sign is used to block the passage to certain areas forbidden to be entered as e.g., pond fields during the ālup holiday; an entire village area during tūngaw holiday; the place where someone has died a violent death, for two or three days following the event; a forest where a trap for wild animals has been set. It may also be placed against a tree to prevent it from being cut down.
