CNN — Sesame Street does it again and taking on those tough issues.
The children's TV series is expanding its "Little Children, Big Challenges" series by introducing Alex, a muppet whose father is in jail.
Alex is part of sesame workshop's online tool kit aimed to help kids understand and cope with parental incarceration.
Some find the character a bit odd, but one in 28 American children reportedly have a parent in prison.
Sesame Street has used muppets to tackle other tough issues like divorce, hunger and military deployment.
