The wedding cake whistled in anger - it accomplished this by shifting its mass about to create an orifice through which it channeled a directed flow of air.

It was used to having its way. It did not like to be toyed with. The chomp had teased it with the anticipation of a satisfying crushing to a pulp, but had rolled away at the last instant. Then the nuisance had screamed something that was beyond the cake's abilities of comprehension.

Suddenly, it felt a sensation in its base tier. It whirled around in surprise. A row of chomps stood very close to it, licking their lips like they did after a successful chomp. They had chomped off chunks of the base tier when it hadn't been paying attention...

"Second rank, advance!" Shouted the protagonist chomp.

A row of chomps emerged from where they had lain hidden behind a hut, and chomped on the base tier of the cake from the other side when it was distracted by the first rank.

"Good going chomps. Keep at it! We need to whittle that base tier down!"

Now while the cake was distracted by the second rank of chomps, who taunted it and dodged its advances making sure they were just out of reach, the first rank took advantage of the situation and resumed their chomping.

This continued till the lowest tier of the cake was smaller than the second lowest tier. The plane of the tier was now a rough concentric circle which lay inside the circle of the tier above it.

The cake began to wobble, teetering to one side and then the other. Consumed by rage, it tried to crush the chomps instead of regaining its balance.

Finally, it came crashing down like a tree chopped at the base.

Victory!
