Yasmin Cordero, while what can appear as an unimportant side character, actually served a very important part of the movie's plot. When Sid the Sloth went through his emotional breakdown on the iceberg midway through the film, Yasmin Cordero stood in the back, and smiled at Sid, which encouraged Sid to keep going. Yasmin Cordero's kind spirit is what allowed the hero of the movie to fight through his emotional breakdown.
Thank you, Ms. Yasmin Cordero (Ice Age 2: The Meltdown)!! - Sid the Sloth
