You can spot the 85-year-old mouse in the quickest of cameos in "Frozen" at a place Anna discovers after she ventures into the cold forest. A tiny Mickey Mouse plush toy sits on one of the lower shelves in Wandering Oaken's Trading Post and Sauna.
It was revealed through a series of "Fun Facts" circulating throughout various "Frozen" fan pages that if Olaf had melted while in front of the fire, that would also have constituted an act of true love.
