In children, the classic "currant jelly" stool - representing a mixture of blood and mucous - is typically found in intussusception, which is a "telescoping" of the bowel. Imaging such as a CT scan and ultrasound may be helpful. A contrast enema is typically the standard to evaluate this.
Any type of infection or inflammation may also be possible. I would suggest sending the stool off for culture to rule out a bacterial infection. Endoscopy can also be considered.
If the symptoms continue, I would suggest a referral to a pediatric gastroenterologist.
Followup with your personal physician is essential.

I was told it points to an inflammation in the intestines. I'd at least call your pediatrician and see what she/he says. My kids have had the same thing, and it was usually around the time when they were sick.
Green stool (not jelly-like) can sometimes be attributed to having consumed food or juice drinks that are purple in color. The first time it happened to one of my kids I was shocked, but I was able to determine it came from drinking purple juice drinks, however, the stool did not have green mucous, the stool itself was green.
