They’re exploring the back story of Karli, a bright green, yellow-haired friend of Elmo’s

‘Sesame Street’ is taking a new step to try to help kids navigate life in America — it’s tackling the opioid crisis.
Sesame Workshop is exploring the back story of Karli, a bright green, yellow-haired friend of Elmo’s whose mother is battling addiction. The initiative is part of the Sesame Street in Communities resources available online.
Karli had already been introduced as a puppet in foster care earlier this year, but viewers now will understand why her mother had to go away for a while.
