The spider experiments with new ways to move its eight legs, instead of the boring old L-R-L-R-L-R-L-R.
Perhaps a waltz?
L-r-r R-l-l L-r-r R-l-l, swaying side to side.
Or, a variation:
L-R R-L L-R R-L
Or something more daring:
L-r-L [pause] L-r-R [pause] L-r [repeat]
While in the middle of these complex steps, a bird, uninterested in dance, flies down and snatches the spider up in its bill.
H-L-P H-L-P !
