Scrat was an acorn-obsessed saber-toothed squirrel that lived during the ice ages, attempting to store his prized acorn. He is a supporting character in Ice Age, a major character in Ice Age: The Meltdown, Ice Age: Continental Drift and Ice Age: Collision Course, and the tetartagonist of Ice Age: Dawn Of The Dinosaurs.
During the days of the ice age, Scrat took an acorn with him everywhere, hoping to find a place to store it for the winter. Scrat also went out looking for other acorns so as to further his storage, looking all over for acorns and nuts.
History with the Macy's Parade
Scrat made his first appearance in the Macy's Parade in 2015, to promote the new film, Ice Age: Collision Course. He debuted alongside Ronald McDonald, Angry Birds' Red and Sinclair's Dino. The balloon depicts Scrat chasing after his beloved acorn, which can fit 15 million standard-sized acorns inside. Scrat is one of the only balloons that is accompanied by a novelty balloon, the other two being Charlie Brown and Pikachu. He still appears as of 2017.
