The Seaside Amusement Park is the local amusement park in Greenpoint down near the shore. In footage, it has a ferris wheel, merry-go-round and various attractions including a haunted house attraction. Old Cap brings the kids here on his pension money in Mush And Milk as does Mary Kornman when she grows up and becomes a teacher. When Alfalfa tries to be a detective in Hide And Shriek, he, Porky and Buckwheat get trapped in the haunted house attraction.
The park footage was actually stock footage from the Venice Pier.
