What a strange sound. The little Pokemon’s tail gave a small, involuntary flick. Mewtwo had to process what they just heard for a few moments.

‘Was that a song you were doing before?’

“Correct, little one. It’s a kind of song called a lullaby. A slow song that can help one relax enough to sleep.”

Rebecca gently patted the little Pokemon’s back still smiling. At least they weren’t scared anymore.
