the Fish on the Bus Go...

We've been singing "The Wheels on the Bus" song a lot these last few days. At first it was just about having fun with the hand motions, which Molly enjoyed. Then, we started asking Molly "what's next?". She would specify "up-down" for "the windows on the bus go up and down", and "babies" for the babies on the bus go wah-wah-wah", etc. And then she started breaking out of the mold. One of her favorite requests now is "fish", as in "the fish on the bus go splish splash splish" (or whatever we feel like making the fish do at the moment). I guess if Dr. Seuss can put three fish in a tree (fish in a tree? how can that be?) Molly can have fish on a bus, right?
