As you’ve seen, our young man has gotten quite good at swimming – both relative to how he was earlier, and in absolute terms. But not to worry: the lad still gets up to plenty of goofy and silly fun in the pool. Check out these videos.

When he’s in the little pool, he likes to show off some routines. All of which he makes up on the spot, of course. Like “Monorail Explode” or “Balloon Circle Explode.” It’s kind of like modern, interpretive dance, maybe?

Here he is in his “Famous” phase, featuring maneuvers like “Famous Shipwalking” and “Famous Airplane Wing.” Also “Famous Train Whistle.”

Spinning around like a, uh, like a corkscrew in a swimming pool, maybe.

Finally, here’s our hero, and Mommy, viewed from 20 stories up. Note that Nyan is (successfully) walking while wearing diving flippers.
