Automatic terror machine: When blood covered bank cards are found, Mr. Monster is put on the case. He discovers that the bank owner, Ebenezar Potter, has sold his soul to the devil for profit. As a result, yiddish money-demons are working for him instead of the high cost of bank machinery. Confronting Mr. Potter, Mr. Monster inserts his Monster Card, an ancient Hebrew bank card, which allows him to reprogram the money-demons to kill Mr. Potter.
On the job: Mr. Monster is hired to exterminate building demons. When he is double-crossed by the owner, Mr. Monster leaves the demons to their work, namely destroying the building.
