I can't write a riddle, but here are two for you to solve:

1. I have a heart that doesn't beat, I can't be eaten because I'm not a sweet treat. What am I?

2. I can be brown or white, but I'm not the same every night. I'm small but mighty, bringing joy with a bite. What am I?

Based on the given phrases, here are the step-by-step solutions for the riddles:

Riddle 1:
1. Find a pen and paper or any writing tool.
2. Write down the phrase "Need to write it? This will do, Go find one.".
