You can get this pin by collecting a certain number of seasonal pins. Seasonal pins are only available for a short time.

This is the amount you need:

Level	Collected
	2 seasonal pins
	5 seasonal pins
	10 seasonal pins
	20 seasonal pins
	50 seasonal pins

After reaching the 5th level, you can level this pin again with the same number. After that, the color no longer changes, but a number appears on the pin. This shows other users how many times you have reached the last level.
