Is he thirsty? Ken has to stop and assess. His mouth is a little dry. They haven't done much running around yet, but if they're going to keep active, hydration is important....

"Thanks." He tries to peer up at Wormmon. "What about you?"

Wormmon puffs himself up. "That much running was noth...ing..."

Puffing up has turned into huffing and puffing. Ken tries to catch the other boy's eyes, then discreetly holds up 2 fingers. A water for the worm, too, please.
