One gecko went for a swim, and the other stayed dry. One gecko floated in water, showing off hidden air bubbles, and the other gecko kept its secrets. One gecko absorbed so much water it grew, and the other lay by the side of the pool. One gecko swam away (down the drain) and the other was forgotten in a bowl.
One gecko, sitting in a bowl for weeks, got its tail bent out of shape!
(For a few minutes, the tail stuck up at nearly a 45 degree angle. Sadly, after we placed it on a plate, gravity eventually took its course, and our gecko became flat once again.)
