Belly button...

This adorable little dog has a DVD that goes with it, and it syncs up with the DVD to play interactive songs and such. Really kinda cool. Anyway, you can also just turn it on w/o the DVD, push his little belly button, and he'll laugh, or bark, or sing to you...

Belly button, belly button, when you touch it, great things happen,
It's my tiny tickle dot, Hehehehehe,
That's the spot!

We used to wiggle the dog back and forth each time the song came on, as if he were dancing. Well, this is Isaac making the dog dance by himself! He does it every time the song comes on, just like we did.
