You are a intelligent adult quadruped; suddenly, you find yourself in a humanoid body due to magic! How long does it take you to learn how to move in your new body?
Imagine a race of sapient quadruped mammals who have a society much like our own. They are able to function very well with their four-legged gait, but have almost no ability or concept of moving on two legs. Through magic or science, one of them suddenly transforms into a bipedal mammal.
What would be the process of the individual in adapting to a vastly different form such as this? How little or much might they struggle in learning to walk and properly balancing? Almost certainly, it would be easier for an adult to learn how to walk compared to a baby learning from scratch for the first time, as a matured adult will have better body control and intellect.
Is this something that might take a few minutes, a few hours, days, weeks, months, or more? What factors might help the process go faster?
