While on set to shoot his new cartoon, Lil' Munster found himself in quite a lot of a trouble. After incidentally ingesting a growth formula , he grew to the size of a sky scraper. Unaware and possibly under the influence of the mysterious substance, 'Not so Lil Munster' began to treat the city as if it was a set for his show. While he wasn't trying to cause damages to the city, his magnified size also magnified his clumsiness.
Attempting to continue his performance for his show, the monster mouse attempted to juggle. This resulted in massive bouncy balls flying everywhere, damaging the surrounding buildings. They also landed on his head, knocking him off balance and sending him into the buildings as well. Luckily for residents of Metropolis, Big Munster's trip ended up sending him into the ocean which, given his highly absorbent attire, prevented him from moving until the growth formula wore off.
To no one's surprise, this is not the first time Lil' Munster has caused issues in downtown Metropolis. Thankfully, the damages to the city were minor and no one was harmed in the making of the film.
