Stefan Karl Stefansson, known for playing Robbie Rotten in “Lazy Town,” is currently battling stage 4 pancreatic cancer.

The actor’s sickness is no longer responding to any of his treatments.

The actor, who is widely known for being Robbie Rotten and whose character won Reddit’s “Meme of the Year” in 2016, is currently fighting to live out stage 4 pancreatic cancer, the Inquisitr reported.

Stefansson was diagnosed with pancreatic cancer in September last year and has undergone multiple surgeries and chemo treatments in the past nine months.

On June 2, We The Unicorns acquired an update from Stefansson’s representative, saying that they were hoping that it would be their last visit to the doctor regarding his cancer.

In a recent Facebook post translated from Icelandic by the site, Stefansson’s wife, Steinunn Olina Þorsteinsdóttir, shared that her husband’s illness is no longer responding to any kind of treatment.
