Scrat, the supporting star of the Ice Age franchise, is putting one last acorn into a huge and very neatly arranged stash, but it keeps popping up. He jumps on it – once too often, and the whole stockpile falls through a knothole in the tree stump. The acorns and Scrat fall a very long way; with Scrat trying to collect them all on the way down. After appearing on the DVD release of Ice Age in late 2002 and receiving theatrical billings with Fox family films, Gone Nutty was nominated for an Academy Award for Best Animated Short in 2004, losing to Harvie Krumpet. —IMDb
Carlos Saldanha (born July 20, 1968) is a Brazilian director of animated films. He was the director of Ice Age: The Meltdown (2006), Ice Age: Dawn of the Dinosaurs (2009) and Rio (2011), and the co-director of Ice Age (2002) and Robots (2005). Saldanha was born in Rio de Janeiro, Brazil. He left his hometown in 1991 to follow his artistic instinct and passion for animation. With a background in computer science and a natural artistic sensibility, he found New York City the perfect locale to merge these skills and become an animator. He attended the MFA program at New York’s School of Visual Arts, where he graduated with honors in 1993, after completing two animated shorts, The Adventures of Korky, the Corkscrew (1992) and Time For Love (1993). The shorts have been screened at animation festivals around the world. At SVA, Saldanha met Chris Wedge, one of the cofounders of Blue Sky Studios, who invited him to join their growing team of artists. —Wikipedia
