Sonic's hands are small and blue, just like the rest of his body. They have three fingers and a thumb, all of which are long and slender and end in pointed tips.
Here are some additional details:
* His palms are smooth, without any lines or wrinkles.
* His fingernails are also blue, matching his skin.
* He uses his hands for a variety of things: running, punching, grabbing, and even picking up objects.
