The central idea of every Ice Age film is that your herd (family) isn't necessarily the one you're born with but the tribe that protects you and loves you unconditionally. Even though Sid's sloth family abandons him, Manny and Diego never will. The subplot with Peaches reminds viewers that true friends accept you as you are, not under the condition that you dump another friend first.
