//Nick's Prank (Story inspired by Zootopia Teaser Trailer)

//Judy the bunny and the goat are walking on the street. 
//Nick the fox sees them and decides to play a prank on Judy.
//When Judy passes Nick, Nick puts out his foot and trips Judy.
//In panic, judy pushes the goat walking in front of her, so the goat falls down as well.
//After seeing them both fall, Nick hums with joy.
