Bad Day at Peril Park is the 25th episode from the Mega Man animated series.
A young boy named Bobby is running away from a group of robots who are trying to kidnap him. However, these aren't normal robots. These are really humans that have been converted into robots. After Mega Man saves him, Bobby tells him that there's something odd going on at the new amusement park "Fun World". The owner of the park is really Dr. Wily and he is capturing humans and hypnotizing them to make them think they are robots.
Mega Man, Roll, Rush and Dr. Light make their way through the park and encounter Wily's robot masters along the way. But, Mega Man doesn't plan on letting them stop him from shutting down Wily's dangerous theme park.
