Kaiketsu Zorori - Season 1 Episode 36 Clash! The Great Mecha Ishishi & Noshishi Plan

Zorori and the boars arrive in the kingdom of Pikkarin, where people who do good deeds are given a stamp. Receive 12 stamps and you are rewarded by the king. Zorori refuses the offer because he has no intention of doing anything good. Once inside the kingdom, they find wanted posters for Ishishi & Noshishi everywhere. Before they have a chance to escape or even wonder why they are being looked for, they are apprehended by the police. When they are taken to the police station however, they find a party waiting for them in their honor. Supposedly the boars returned the kings treasured golden wig the other night. It is at the party where they find out that it was not the boars who did the good deed, but a pair of identical robots. Their creator is Dr. Gaon, once again creating copies. The boars are outraged and challenge their knock-offs to prove they are better, but lose to them every time. Zorori joins in and challenges Gaon and his creations to a good person stamp contest.
