It's been a while since the first couple of Grandpa T-Rex cartoons (handily labelled so you can check them out if you've forgotten about them); the series all about an old, curmudgeonly, early Cretaceous dinosaur living in a late Cretaceous world. But good news! He'll be appearing a lot more often from now on, because he's very, very easy to draw and jokes about the elderly are ten a penny. He's basically like your grandad, except a T-Rex. What's not to love?
