Create a fun and interactive "Panda Calculator" that helps users perform basic and advanced calculations with a playful design.

Project Overview:
- Develop a calculator with a panda theme, incorporating both basic (addition, subtraction, multiplication, division) and advanced calculations.
- Occasionally introduce a random error by adding 1% to an operation result, rounded to a whole number, to keep users guessing without being obvious.

UI/UX Design and Flow:
- Design a panda-themed user interface with a consistent color scheme and panda illustrations.
- Implement jumping animations for a panda character, especially when a button is pressed or an operation is complete.
- Include playful sound effects for button clicks and other interactions to enhance the user experience.

Core Functionality and Logic:
- Basic calculator functions of addition, subtraction, multiplication, and division.
- Advanced calculation features (which should be specified if more details are needed later).
- Logic to randomly apply a 1% increase to operation results occasionally, ensuring it's subtle and does not disrupt user trust too much.

Best Practices:
- Ensure responsiveness for both desktop and mobile devices.
- Maintain smooth animations and ensure sound effects do not delay interactions.
- Provide clear instructions or indicators for when the calculator is operating on the 'Panda Mode' of introducing errors.
- Test the application thoroughly to make sure all functionalities work as expected across different devices.
