The last person that answered this is an air head, the true answer is the porcupine. Also, Echidna.
These are called quills. They come loose and get stuck in the skin of animals that they come in contact with.
Porcupines are nocturnal and solitary animals. They are herbivores and primarily eat bark, leaves, and plants. Porcupines are known for their defensive behavior of raising their quills when threatened.

Many farm animals have horns. Those animals include: Cows Bulls Goats Rams Certain sheep Deer (a male is called a stag, the one with horns) Moose
Animals that eat porcupines usually flip them over and attack their bellies, which have fewer quills. They may also target the face or head to avoid the sharp quills on the back. Some predators, like fishers and wolverines, have thick fur that protects them from the quills.
Bighorn sheep, elk and moose are wildlife in Montana that have horns.
Porcupines do not have venomous or dangerous weapons, but they possess a unique defense mechanism: quills. These sharp, barbed quills cover their bodies and can easily detach when a predator comes into contact with them. While porcupines are generally not aggressive, their quills can cause significant injury to animals that attempt to attack them. Therefore, while they are not inherently dangerous, their quills can pose a threat to other animals.
