A single crochet increase is really nothing more than working a single crochet stitch in one stitch twice.
Amigurumi crochet patterns make extensive use of increasing and decreasing crochet stitches. That is because it creates the shape of the stuffed animal.
The abbreviation of the single crochet increase: sc inc
