(CNN) — Sesame Street is taking on another tough issue.
The children's television series is expanding its, "Little Children, Big Challenges" series by introducing Alex, a muppet whose father is in jail.
Alex ix part of Sesame Workshop's online tool kit aimed to help kids understand and cope with parental incarceration.
It is also a tool to help caregivers talk about the subject with children.
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.
