In the video, a person is seen decorating a cake with green frosting. The cake is rectangular in shape and has a scalloped pattern on the top. The person uses a paintbrush to apply the frosting and writes the words "Goosebumps" on the side of the cake in a cursive font. The frosting is bright green and stands out against the white background of the cake. The person's hand is visible as they work on the cake, and the brushstrokes are precise and deliberate. The video is shot in a well-lit room, and the focus is solely on the cake and the decorating process.
