A polka-playing band of ten polar bears gathers on an iceberg that's big enough to serve as a stage. The music strikes up, when suddenly-SNAP-a chunk of the iceberg breaks off, and one of the bears floats away. Then-BOINK-must be warming up because another piece of the ice and another musician just crashed off the side. Can you imagine a polka band without the tuba? Counting backwards, the band is eventually reduced toÉnone. But fear not, the bears push their pieces of the iceberg back together, and the show goes on!
