Illustrate a kawaii-style sweet jalapeno with a big smile, designed in a simple, flat-colored vector style. The pickle should have small, cute eyes and a large, cheerful mouth to emphasize its friendly appearance. The character's design should follow a simplistic approach, with minimal details to maintain a clear and straightforward look. The background must be white, and the overall illustration should avoid any sense of depth or shadows, adhering to a flat, filled-in coloring approach without gradients. The artwork must capture the essence of a sweet pickle in a playful and inviting manner, using vibrant but limited colors to highlight its features.
