In The Super Mario Bros. Super Show! episode "Koopenstein", the Swiss Cheese Alps Mayor, when Mario, Luigi, Toad and Princess Toadstool arrived in the village, presented them with the key to the village in a show of appreciation for them having come to defeat Dr. Koopenstein. After giving this key to Princess Toadstool the village key, the Swiss Cheese Alps Mayor led the cheer for Mario, Luigi, Toad and Princess Toadstool after they promised to do their best in defeating Dr. Koopenstein.
Later on, after Dr. Koopenstein was transformed into the Koopenstein Monster and abducted Princess Toadstool, the Swiss Cheese Alps Mayor frantically ran to tell Mario, Luigi and Toad that the Koopenstein Monster was attacking his village; after alerting Mario, Luigi and Toad to this, the Swiss Cheese Alps Mayor led them to the village, where the Koopenstein Monster was going on a rampage. The Swiss Cheese Alps Mayor apparently stood on the sidelines or took cover when Mario, Luigi and Toad began their battle with the Koopenstein Monster, as he wasn't seen in the entire duration of the battle.
When the Koopenstein Monster and Mouser were defeated by Mario and Dr. Koopenstein's own Robot Monster Troopa, the Swiss Cheese Alps Mayor presented Mario with a reward for his help in saving the Swiss Cheese Alps, a pizza covered in hole-filled cheese, which Mario thought were bite marks.
