"Create a 2D animation prompt for a church bus in a mobile video game. Utilize a single color palette to design the bus, ensuring it doesn't appear too realistic. The animation should encapsulate a charming and simplified depiction of a church bus, evoking a whimsical and playful vibe suitable for a mobile gaming experience. Avoid intricate details and focus on creating a visually appealing, stylized representation of the church bus without incorporating any text or additional elements."
