Pico was forgotten at the behest of his father, taking in the explanation about swimming. He knew what running was; it was like that? In water? The boy could identify singular words that triggered at least a slight understanding of what Atatak was trying to say. Remaining still as his father instructed, he watched curiously as the red male sunk into the water until only his head remained above water. It took mere moments for him to realize that his father was moving about in the water, in a different manner than when they'd been pouncing around in the stream near the den.

In no time at all, he was up on his feet, tail wagging furiously as Atatak asked him if he wanted to learn. "Yah!" And with that, he bounded closer, preparing to launch himself into the creek and... well, just start swimming.
