From Homestar Runner Wiki
The Punkin Patch appears briefly in That A Ghost, and it is simply a field full of pumpkins. The Homestar Runner and his friends were looking there to see if they could find a ghost. They didn't find anything, but Marzipan was frightened to be around there, so they instead looked in the graveyard. This may be the Old-Timey version of the Spooky Woods.
"Pumpkin" was previously misspelled as "punkin" in Punkin Stencils.
