Olaf, the optimistic snowman from Disney’s mammoth film “Frozen,” will pay a visit to the animated series “Sofia The First,” as part of new efforts to keep the 2013 phenomenon viable in consumers’ minds.

The character, voiced by actor Josh Gad, will appear in a “Sofia” episode slated for broadcast on Disney Channel and Disney Junior on Monday, February 15, and made available via the Disney Junior mobile app as early as February 8. The show will be the second episode, titled “The Secret Library: Olaf and the Tale of Miss Nettle,” in a four-part story arc. Megan Mullally will return as the voice of Miss Nettle, a role for which she received an Emmy Award nomination earlier this year. Eric Stonestreet and Hugh Bonneville recur as Sofia’s flying horse Minimus and the Narrator, respectively.

On February 2, Disney Publishing Worldwide will release an illustrated storybook and e-book based on the episode.

Disney’s “Frozen” will be presented on Disney Channel at 7 p.m. eastern on February 14 for the first time.

The company has reason to draw more attention to the 2013 animated classic, which was inspired by the Hans Christian Andersen story, “The Snow Queen.” Disney unveiled last March its intention to produce a sequel.
