Big thanks to  Ferndragon for this drawing of Rocky that he did on his free requests stream last night.

As you can see that Rocky feels that way, it's because Rocky had a bad day. First, when he was driving, he had drove his car over a nail which had caused a flat tire. This made him stressed and that he needed to replace the tire with the Tire Replacement equipment that he has in his car. After finishing, he put everything back inside the trunk.

Rocky then went back to his car to unlock the door, but he had accidentally snapped the key in half, making him frustrated than before (Thankfully, the alarm wasn't armed). He called a Tow Truck to come take him and his car to an Auto Repair Shop in the city. As he was waiting for the key to be removed, he sat, glumly.
