What it is for

A limb with no joint can do anything. The style exists because it lets a body stretch, coil and snap in ways a drawn skeleton cannot, and even in a still frame that freedom reads as energy.

How it works

Every limb is a tube of constant width that curves in a single smooth arc. The body is circles. The hands are gloves, which removes the problem of drawing four knuckles at speed. The eyes are circles with a wedge cut out, which is why they read as a direction rather than as a gaze.

When to use it

Use it for anything that should feel old, loose and a little unhinged. Avoid it when the character needs to carry weight or seriousness, because a body with no joints cannot hold a pose that means anything.

Told apart from its neighbours

Noodle Limb is the modern descendant: long bendy limbs, but with a shoulder and a wrist that still work. Funny Animal shares the round construction but keeps real joints. Bean Construction is about the torso, not the limbs.

Where it is used

It carries a mascot, a title card and a game character, and it is the fastest way to make something read as period without naming a decade in the picture.

  • 1920s and 1930s theatrical shorts
  • Modern games that borrow the period look

The prompt

Replace the blanks with your own character, keep the rest. Then run it on an image model.

<character>, rubber hose cartoon style, arms and legs drawn as smooth curved tubes with no elbows and no knees, bending anywhere along their length, a body built from simple circles, white gloves on the hands, round pie cut eyes with a wedge missing, a line of one even weight all the way round, flat black and white with a few flat colours

Run it

What goes wrong

What comes back most often is a modern cartoon with slightly bendy arms. The fix is the pie cut eye and the white glove, which are the two details a model will not invent on its own.

Leave out

joints, elbows, knees, anatomy, muscle definition, gradients, modern proportions, a tapered line

Watch for

The tubes are the entry. Say no elbows and no knees in the same clause that asks for curved limbs, because a model knows how an arm is built and will put the joint back unless it is told twice.

Questions

A pie cut eye reads as a direction rather than as a gaze, which is what lets a character look somewhere without a drawn pupil. It is also one of the two details that fix the period, alongside the white gloves.
