A cartoon picture of a bunch of zombies in a field

Design a one-page digital illustration that features an adorable and cheerful zombie world bursting with happy colors. Populate the scene with cute, zombified characters engaged in quirky and humorous activities, such as a zombie picnic, a dance party, or a gardening club. Infuse the entire composition with a vibrant and inviting color palette to create a fun and whimsical atmosphere that defies the typical gloom associated with zombies.
