Read the excerpt from Hayden and Henry Go to Fenwick Island:

Hayden was surprised to hear his twin say this. Henry had always been the confident one, always up for taking risks. Giving up just wasn't his style. It upset Hayden to see his brother looking so down and upset, and he knew he had to do something to comfort his brother as Henry had done for him so many times before. Like bolts of lightning, facts that Hayden had read about jellyfish began to zigzag through his mind. 'Of course!' he thought.

"Henry, remember how I said that the average water temperature in the Atlantic would be around 50 degrees just now?"

"That's not helpful, Hayden," Henry sighed. "I'm prepared for the cold, just not the possibility of pain."

"No, no, that's not my point," Hayden continued excitedly, "Jellyfish prefer warm waters! It's far too cold for them to be out and about in the ocean right now. The probability that you'll see a jellyfish tomorrow, let alone be stung, is very low," he finished triumphantly.

A smile spread across Henry's face. "That's brilliant news, Hayden! Thanks so much. I can always count on you and your random knowledge to save the day!" he laughed, throwing his arm around his brother's shoulder.
