The Tyrannosaurus rex opened its mouth and roared. Frank and Joe pulled more basketballs from the gutter and threw them into the hoop beside the dinosaur’s head. “We are halfway there!” Frank yelled. “Keep going.” They grabbed another ball, then another, and tossed them into the hoop. Each one was painted white and purple, which was supposed to make them look like dinosaur eggs. The basketball hoop was shaped like a nest. The boys had discovered the game this afternoon, and they’d spent the last few hours inside the arcade, shooting hoop after hoop. Dino Ball (which is what it was called) had earned them more than fifty tickets. If they won fifty more, they could have their choice of prizes from the arcade. “There you are!” Mrs. Hardy yelled across the crowded arcade. “We’ve been looking all over for you. This place is packed.” “Just . . . one . . . more!” Joe said. The timer ticked down. He tossed the last egg into the nest. It went through, and the machine spit out ten more tickets.
