Swiss Cheese Alps Mayor
From the Super Mario Wiki
In The Super Mario Bros. Super Show! episode "Koopenstein", the Swiss Cheese Alps Mayor, when Mario, Luigi, Toad and Princess Toadstool arrive in the village, presents 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 leads the cheer for Mario, Luigi, Toad and Princess Toadstool after they promise to do their best in defeating Dr. Koopenstein.
Later on, after Dr. Koopenstein is transformed into the Koopenstein Monster and abducts Princess Toadstool, the Swiss Cheese Alps Mayor frantically runs to tell Mario, Luigi and Toad that the Koopenstein Monster is attacking his village; after alerting Mario, Luigi and Toad to this, the Swiss Cheese Alps Mayor leads them to the village, where the Koopenstein Monster is going on a rampage. The Swiss Cheese Alps Mayor apparently stands on the sidelines or takes cover when Mario, Luigi and Toad begin their battle with the Koopenstein Monster, as he is not seen in the entire duration of the battle.
When the Koopenstein Monster and Mouser are defeated by Mario and Dr. Koopenstein's own Robot Monster Troopa, the Swiss Cheese Alps Mayor presents Mario with a reward for his help in saving the Swiss Cheese Alps, a pizza covered in hole-filled cheese, which Mario thinks are bite marks.
