You’ve encountered memory snow. This counts as a common creature encounter for the purposes of levelling, but does not count as a Random Event for levelling or MP. There will be no further admin/re intervention. If you choose to follow this creature, you do so at your own risk, however, just having it in this thread is enough to satisfy your levelling requirements. (You may not kill your rare creature without admin permission. )
Memory Snow (Common): When shaped, the fallen snow seems to retain a memory of that shape and will reform if disassembled (snowmen who are knocked over or who melt will immediately reform when possible)
