Ulf is first seen at the Snuggly Duckling pub during the song "I've Got a Dream". Later on, Ulf assists some of the other major thugs in their mission to rescue Flynn Rider from prison so that he may rescue Rapunzel from the villain Mother Gothel. Ulf is last seen at the end of the film acting as a mime in front of the crowd (although everyone is bewildered by the act); Flynn remarks that he assumes that Ulf is happy, as he never told him otherwise.
In Tangled Ever After, Ulf can be seen at the wedding ceremony sitting alongside the other thugs.
Ulf is seen in Corona Castle during Eugene's verse of "Life After Happily Ever After. He, along with most of the main thugs, appears to have become one of Eugene's closest companions outside of Rapunzel and Maximus.
In "What the Hair?!", Ulf appears in the castle after Eugene explains that one of the guards is terrified of mimes (as they see things that aren't there). He later shows up at the Snuggly Duckling eating an invisible sandwich.
