You go with your impulses and take the little league, baseball uniform along with the other baseball equipment that came with it.
Without hesitation, you start dressing up from the undersized baseball shoes, socks, and pants to the jersey, and then finally a ballcap. The clothes felt too tight on you, and a look at the mirror confirmed it, as you saw the reflection of a British teen wearing clothes for a boy half his age. But that was about to change when you felt a tingling sensation.
The changes had begun, firstly by decreasing your height, diminishing your small trace of body hair, and replacing whatever muscle definition you had with baby fat. After that, your features become more juvenile and cherubic as your face became rounder, and your nose became a button nose —you could see the hair underneath your cap receding into a buzz cut and changing colors from light brown to blond. And with all of that, your transformation was over, and the uniform was now a perfect fit.
It was a bit perplexing for you to realise that the British teen you were a few moments ago is now this all-American, eight-year-old kid. Ironically, his (or more appropriately *your*) age matching the number on the back of the jersey.
"Woah…" You say in shock, barely ignoring the youthfulness of your voice. "What should I do now?"
