Swim (many legs)
The swim of the game cycles for many legs: the legs paddle in turn, two groups opposite each other, with the claws held forward, looping every 0.8 seconds for as long as a game has the character afloat.

What it is for
Swim (many legs) is the swim of the nine game cycles, written for the many set: paddling the legs one after another from back to front with the claws held forward, bobbing, rather than the upright swim's two-armed stroke.
The principle it shows: overlapping action
The legs and the shins both paddle on the same 0.8-second rhythm, but the shins lag a quarter-turn behind their own leg, so each stroke bends through rather than sweeping as one stiff piece. The body's own small bob keeps that same shared rhythm underneath, rather than a faster beat layered on top the way the upright swim's legs and tail use.

Try this
Paddle the left leg 35 degrees instead of 22. The stroke becomes a much harder paddle, pushing far more water with each kick.
In the program:

How it differs from Swim and Climb (many legs)
Swim is the same idea paddling with two arms on a two-legged body rather than legs by the set. Climb (many legs) is the other cycle written for this body with no foot-planting math, reaching with claws against a surface rather than paddling through water.
