Musk is used in the Wild Monster Baiter in order to attract Wild Monsters to a players base by spraying a scent that monsters are attracted to. It comes in a limited supply, but regenerates slowly over time, and speeds up after upgrades. Musk can also be refilled by spending shiny. It's not used in any other occassions. Musk is technically not a resource.
*Note: Musk was removed from Backyard Monsters as of 7/4/2012
