Surviving Sid is the fourth Blue Sky short film. It stars Sid the Sloth of Ice Age and a cameo appearance by Scrat. It is the third in the series of Ice Age short films, the first being Gone Nutty released with the Ice Age DVD in November 2002.
Sid, the Sloth, takes a school of children out on a camping trip from home, only to find that in typical Sid style, he is not a very good guide and the children he takes with him don't have a very good time. Scrat makes a small cameo appearance in the short, he has swallowed his nut and is struggling to keep it down, in true Scrat style he coughs it up and it is stolen from him. The camping trip leaves some of the children somewhat traumatised. Sid tries to pick a flower, but somehow this has led to a tree falling, which then hits a rock, which causes a chain reaction and hits a series of larger rocks, until eventually hitting a large iceberg. The iceberg then carves out a u-shaped valley, which Sid later names the Grand Canyon. Afterwards the kids get so annoyed with Sid that it ends with them tying him up. At the end of the short movie (20,000 years later in the present day) it shows a father and son beaver looking over the Grand Canyon with the son asking who made it. The father replies "Nature or a being with infinite wisdom."
