Marco grinned as it was proclaimed to be Zenith Fun Day, something that he knew happened once in a while, but not often enough. He supposed Harper didn't, though, and when he caught her looking at him he flashed a thumbs up at her. "Need help?" he asked her as he neared the climbing wall, moving to the side so he could give people room to climb, but also give Harper a boost if she needed it. The other guys were taller than him, and probably didn't need the boost. Hell, he kind of remembered a similar obstacle on the ropes course that he kind of remembered Tobias being pretty good at, even though he seemed scared at the start.
He leaned against the wall, watching the others in the group as climbing started. "Maybe there's a treasure at the end," he considered, then laughed. That seemed like such a childish thought, but childish thoughts seemed 100% appropriate for a bounce house day.
