Ep 6. Brainzburgerz / Chuckle City

In Brainzburgerz, the gang discovers a sinister plot by the evil Rippen to take over fast-food restaurants across the Multiverse and turn everyone into mindless zombies. To stop him, Penn and his team visit a world where fast-food chains have become the primary source of power. They sneak into a restaurant and try to foil Rippen's plan by stopping his zombie army before it can be activated. But with Rippen's goons hot on their heels, they will need all their wits and skills to save the day.

In Chuckle City, Penn and his friends visit a world where everyone has to laugh constantly or face dire consequences. But when Rippen pays a visit, he steals a powerful Laughing Crystal that controls the laughter in the city. With the help of their new friend, a serious local named Chip, the gang sets out to retrieve the crystal and restore order to Chuckle City. Along the way, they face challenges such as a giant laughter squid and a sinister laughter robot. But ultimately, their determination and teamwork prove to be the key to success.
