I think that Crash and Eddie are twins, but does anyone think that they might just be brothers?

Good point, they aren't identical. Crash has Blue eyes, Eddie brown. Crash has a rounder nose, Eddie's is más pointed. Eddie has a stripe down his nose, but Crash does not. Thanks for answering!

youre welcome :)

Ok. Thank-you for answering!

And this comic strip was made in partnership with Blue Sky Studios (at least I hope it is), therefore being a story of the actual Ice Age trilogy. In other words, the authors of this comic strip made them into twins if they were not already.
