Option 1:  Of course Elly loves pranks! She is always prowling around the locker room and leaving pawprints all over the other players hockey sticks. Sometimes she would sneak a fake rubber bird into the middle of the locker room as if she had made a fresh kill. Sometimes she replaces the snacks with rubber mice as well. One of Elly's favorite pranks though was replacinf the puck mid practice with a rubber puck that was super super squeaky. They team couldnt help but laugh and finish the rest of practice with the squeaky puck. They keep the puck in the locker room whenever they need a little extra light heartedness before or after a game. 

But she always makes sure nothing is ever harmful. It's important to have fun but never to hurt the other players or ruin their stuff. Everyone needs a good laugh or a joke and it keeps the morale up.
