Proper story format

They go outside to be greeted by snowballs. "I didn't see that one coming..." Pietro exclaimed and there a snowball at Bruce and Steve, who has threw the snowballs at them. Wanda sits down on a bench and used her magic to make a huge snowball and blasts it at Pietro. Pietro dodges it and it hits Natasha. "Right. That's it." Says Natasha angrily. Wanda smirks and send lots of smaller snowballs her way. Natasha dodges them all whilst making a snowball and throws it at Clint. Clint thinks that Tony threw the snowball at him and those one into Tony's mouth. Thor is confused and build a huge castle- a life sized castle- and sits inside it. Everyone looks surprised as they share in see at the awesome castle before them. "Steve, inciate plan." Says Bruce. Bruce and Steve walks off in the background leaving the team. They build a snowy hedge maze that no one can see over and reinforce it with ice so no- one can break it. When the team turn back, they realise that Wanda and Nat had disappeared. Everybody panics and starts shouting for them. Then, loud screaming and shoutingbfrom coming from Thor's snow castle. They all run through the made and reach the castle where snowy Wanda and Natasha bundle out of. "You on?" Pietro asks.
"I'm fine." Wanda replied. You guys all got seriously tricked. By us four. "FOUR?" Bruce asked.
"Come on Bruce. You and Steve helped ALOT. You build the maze. All we had to do it scream and shout whilst core ourselves in snow." Natasha said with a wide grin on her face.
