The giant chocolate bunny might help you if you kill it.
I'm from over fifty years ago. How am I supposed to get back?
1953. A ninja walked by on some railroad tracks one day. All of a sudden, a minecart rolled up behind him and knocked him to the ground. Before he had time to even blink, he hit his head on the metal rail and was out instantly.
When he woke up, he was lying on the ground in a candy store. Everything seemed hazy and unreal around him. The cashier in the store told him it was 2006, which was over 50 years ahead of his time.
The ninja askes if there is any way to return to his own time. According to the shopkeeper, he has to kill the giant chocolate bunny to grant a wish, which he could use to return to his own time.
After thanking the shopkeeper, he stepped outside into the bitter cold to face the giant. He grabbed a piece of timber on the way out, prepared to use it to fight. But as he stepped outside, he realized that he had underestimated his opponent.
The ninja chucked the piece of timber at the giant, knocking it off balance. In doing so though, its walking stick flew up and knocked the ninja to the ground, slamming his head in the hard snow.
He woke up covered in a cool sweat, lying in a puddle of blood. He was lying stiff on the railroad tracks, trying to wrap his head around what just happened.
