Mr. Carpainter

From Mother - Wiki on Neoseeker

Mr. Carpainter is a normal man who has been taken over. When he abducts the evil Mani-Mani Statue, it turns him crazy, and he starts to take over Happy-Happy Village. The statue turns everyone into a lover of blue, and then they make the entire town blue. Nobody has any idea they are under any mind control until this is sorted later. The only way to get him free is by having him knocked out with the Franklin Badge, then engaging in a battle with him. If you beat him, he will give you the key to rescue Paula, which he kidnapped. Afterwards, the entire town will turn back to normal.

Appearances
