OK, Boomer!

Brief Description
Honestly, Bob... You ignited 3 fireworks in the middle of the road, what did you expect to happen?

Plot
Bob is walking slowly with a cane. Suddenly, he throws the cane away indicating he is in a good shape and has lots of energy despite his age. Bob pulls out 3 firework rockets, the same we light on July 4th, and impale them to the ground. The rockers are put in a row and Bob passes a lit match, lighting their fuses. The 3 fireworks detonate and fly away from Bob.

The scene switches to Roxy who comes out of a manhole, having a bag of money, indicating she stole it from somewhere. She kicks the lid to close the manhole on the street, but then a firework enters into a storm drain, scaring her. The firework immediately flies outside the manhole, raising the lid to the sky. Before Roxy manages to react, the lid falls down again and crushes her head.

The second firework crushes on the side of a truck that carries salt. Just next to the truck is Shelldon. The rocket hit the truck but Shelldon wasn't hurt himself. He sighs out of relief he survived, but immediately after a large mass of salt falls through the hole the rocket created on the truck, covering Shelldon. Shelldon manages to pull out his head from the salt mass, but the salt starts to melt his body and skin because he is a snail! First, his facial skin falls off, along with his moustache. Then, some teeth, his eyes and his facial muscles also fall off.

Lastly, the scene switches to Bast who is enjoying an apple. Bast hears something and before he reacts, a rocket falls from the sky inside his mouth, "nailing" him to the ground. Bast screams and tries to do something, but the rocket explodes, destroying his head, while Bast's brain is thrown away by the explosion's force.

After watching what he caused, Bob brings his cane again and leaves pretending to be a helpless and innocent senior, hoping he will not get caught.

Trivia

 * This is the debut episode of Bob.

 * The similarities between this episode and Trick or Heat are many. In both of them, the debuted character does his favorite hobby/job and he ends up killing the characters around him. Then, he tries to leave the scene quietly so he cannot be suspected for anything.
