Spopovich
is a minon of the evil Babidi. He was once a normal human. But after Babidi did his sorcery on him putting an "M" on his forehead he has gained tremendous power. However he is under the complete control of Babidi. Along with his partner Yamu, Spopovich has been ordered to capture beings with great power. Since you are a geocacher, that means you are a being of great power so he is out to get you.
The only way to stop him is to get him first. Currently he has been spotted on the trails in the Kemin No Mori Park. Find him there, defeat him and get some infomation to find his master Babidi.
