young boy, without goats or companions. In chapter 75 of the Prose Edda book Skáldskaparmál, the names of both goats appear among a list of names for goats. Theories and interpretations Scholar Rudolf Simek connects Tanngrisnir and Tanngnjóstr with the beast Sæhrímnir (consumed nightly by the gods and the einherjar and rejuvenated every day), noting that this may point to sacrificial rites in shamanic practices. In Scandinavian folklore, witches who magically replenish food sometimes appear in tales, the food usually being herring. However, in fear that one would waste away if one were fed the same morsel again and again, folk tales describe the breaking of the herring bones when eating it as a form of precaution. Thematic similarities—bone breaking ending food rejuvenation—between this folk belief and the Old Norse tales of Tanngrisnir and Tanngnjóstr have led scholars Reimund Kvideland and Henning Sehmsdorf to highlight a connection between the two. Modern influence In the Marvel Comics adaptation of the god, Thor usually relies on his hammer to fly. However, in situations where he must transport passengers and/or objects, Thor can summon Tanngrisnir and Tanngnjóstr, both also known as Toothgnasher and Toothgrinder, who arrive already harnessed to his chariot, and can be dismissed with equal ease.

They make their live-action debut in the movie Thor: Love and Thunder where they are portrayed as perpetual screamers, based on the popularity of the yelling goat meme. In the film adaptation of the Speed Racer manga franchise, there is a racecar named after Tanngrisnir, driven by Gothorm Danneskjøld, who is appropriately dressed as a Viking and sponsored by a company called Thor-Axine, referring to the chariot. In the Yu-Gi-Oh Trading Card Game, both Tanngrisnir and Tanngnjóstr are represented as "Nordic Beast" Monster Cards. They are meant to be used in conjunction with other cards representative of other characters and creatures from Norse mythology, including their master Thor. In Rick Riordan's book Magnus Chase and the Gods of Asgard: The Sword of Summer, both Tanngrisnir and Tanngnjóstr appeared. They are called Marvin and Otis, respectively, in the book and they are commonly sacrificed by the god Thor, to be reborn the next day. In Heidevolk's song "Een met de
