You see the Choo Choo train, there are mainly kids aged 2-4 riding on
it, you decide that for nostalgia's sake to ride on it, so you queue
up, pay and get on managing to take up a whole carriage, you note that
there are a couple of other teens who have decided to hop on.
You feel the train begin to move, its heading for a tunnel that you
hadn't noticed earlier, as you enter the tunnel, a strange change
begins to occur. You and the other teens, begin to lose years
extremely quickly, stopping when you reached age 4, you feel your hair
push out from its short cut, giving you long hair for a 4 year old, it
lightens to a blond color, you eyes turn a green color, jeans begin to
form on your legs, a T-shirt with a picture of a cartoon character
appears on your torso, your nether regions feel strange as pull ups
form around it, socks appear on your feet followed by little trainers,
finally a little baseball cap appears on your head, as the train exits
the tunnel you can't stop yourself emitting a childish giggle and
laughing.
