In Progress
Like the Pet and Ball Scales, the various extensions had limits to what would pass on to second generation petz without significant issues.
Leg Extension
The leg extension is pretty obvious, it extends the legs. The first number extends the front legs, the second number extends the hind legs. These are extended by pixels, rather than by percent. What is interesting is that it isn’t actually just the legs themselves moving, but the foot/hand and toe/finger balls remain stationary while the butt/chest ball are the ones moving. The other balls (hip, knee, shoulder, elbow) move in preportion. You can end up with some very odd looking creatures by extending one futher than the other, as the front will move the head with the shoulder, but it will not affect the hind end and the hind end will not affect the front end, including the head. Negative numbers will push the same balls downward, including below the paws.
Front Leg Extension 100
Hind Leg Extension 50
Front Leg Extension -50
Normally, you are going to move these together or in much smaller increments than above. This can be helpful with adjusting a breed that has a sloping topline or to extend the legs. This is how the original breeds get the the stubby legged dachshund from the long legged great dane.
Front Legs Extension 5, Hind Legs Extension 10
Front Legs Extension 15, Hind Legs Extension 5
Front Legs Extension -12, Hind Legs Extension -15
Combining this with the Default Scales and we can see the base file transform into something that resembles the great dane.
Pet Scale 160, Ball Scale 125, Front/Hind Legs Extension 17
Body Extension
The body extension, like the leg extension, works on pixels, rather than percent. It proportionately extends the butt and chest balls away from each other horizontally, and moves the belly ball in proportion between the two.
Body Extension 100, 0, -20
Blah, blah, blah
Body Extension 1000
Blah, blah, blah, blah
Body Extension -100
