It was a quiet morning in hill valley and Marty and Doc were  going on more time travelling adventures when Doc discovered a magic mirror, he showed Marty
"What is it Doc?" Asked Marty
"It's a mirror which leads to another dimension"
"Are we going to go in it or what?!"
"No"
"Or come on Doc"
"We can't we might become a dragon"
"Who cares"
"Fine let's go"
And with that they stepped in the mirror and they whirled around and around and they collapsed on the floor...😵
