Depict a delightful and vibrant cartoon scene set in a grassy field under a clear, cerulean sky adorned with fluffy, intermittent clouds. Center the image on a jovial, anthropomorphic baseball character wearing a festive hat, encircled by celebratory balloons of various cheerful colors. Display a vibrant banner that proclaims 'Happy Birthday!' nearby, swaying in the wind. Show pastel-hued streamers fluttering amidst the breeze, and place a cake shaped like a baseball diamond on a checkered picnic blanket, ready to welcome celebrators.
