Oh, no! Susie Derkins and Mr. Bun have taken an unscheduled trip into the past to when dinosaurs ruled the Earth! Calvin should not have left the keys in the time machine for just anyone to stumble upon but then again he isn’t the most responsible little guy.
I was nostalgic for Calvin and Hobbes so I threw this image together as a lark. The idea that Calvin would just shrug and go play when he discovered his time machine was missing tickled me. Only Hobbes would be likely to show some curiosity or concern when he realized Susie was also nowhere to be found. He would have to badger Calvin into a rescue mission, the result being that both of them would probably get sidetracked by mutants, homework and clones until long after Susie made it back to present day on her own, no thanks to Calvin and his tiger. I just wrote 2 weeks worth of dailies and a full color Sunday strip in my head just now.
