Yellow Question Mark in Blue Bubble Icon

This is a clean and friendly icon featuring a prominent yellow question mark, outlined in purple, centered within a white speech bubble. The bubble itself has a soft, rounded shape, resembling a dialogue box. It's all set against a cheerful blue background that has subtle vertical stripes, giving it a playful feel. The corners of the main shape are nicely rounded, making it look like a typical app or game icon, perhaps for a trivia, quiz, or frequently asked questions application.
