Create a fun and interactive 'Panda Calculator' application. This app should be developed with a playful panda-themed user interface that captures user interest. The calculator is to support basic calculations such as addition, subtraction, multiplication, division, and square roots, with a unique twist by occasionally adding 1% error to the result which is rounded to a whole number, maintaining a humorous yet subtle inaccuracy.

- **Advanced Calculations**: Integrate functions to calculate square roots.
- **Random Inaccuracy**: Implement a logic to randomly add a 1% error, rounded to the nearest whole number, maintaining the whimsical nature without overshadowing utility.

## User Interaction
