While we're bringing our little ones to get their fill of the characters they couldn't get enough of in the original, there are a few friendly faces that add some pizzazz to the new storyline. First off, there's an adorable lizard who I would die for — he reminds me of one of my cats! — and who takes a strong liking to both Olaf and Elsa. Additionally, viewers get to meet Lieutenant Mattias (who's voiced by the especially dreamy Sterling K. Brown), a soldier who's been trapped in a magical forest for 34 years. Not only does he add a lot to the movie by way of backstory, he also has a few hilarious lines that will make you and your kids smile.
