Ep 4. Horrid Henry and the Alien Invasion

Horrid Henry season 2 episode 4, titled Horrid Henry and the Alien Invasion is all about one of Henry's favorite things: science fiction! In this episode, Henry becomes convinced that aliens are about to invade the Earth, and that it's up to him to save the planet from certain doom.

The episode starts off with Henry watching a sci-fi show on TV, complete with aliens, spaceships, and laser guns. His little brother Peter, not a fan of science fiction, walks in and comments on how ridiculous it all is. Henry scoffs at him, insisting that aliens could really exist.

At school the next day, Henry's science teacher introduces the class to the concept of SETI - or the Search for Extra-Terrestrial Intelligence. Henry is thrilled by this, and starts daydreaming about what it would be like to make contact with alien life forms.

But when he gets home from school, Henry's daydreaming turns to paranoia. He starts hearing strange sounds in his room, and convinces himself that they're coming from an alien spaceship that's landed on his roof. His parents and brother try to reassure him that it's just regular house noises, but Henry won't be convinced.

The next day, Henry shows up at school wearing a homemade superhero costume that he's convinced will protect him from the aliens. His classmates laugh at him, but Henry doesn't care - he knows he'll be the one to save the world.

As the day goes on, Henry's paranoia only grows. He becomes convinced that his teacher is actually an alien in disguise, and sets out to prove it. His attempts to unmask the teacher lead to chaos in the classroom, and he ends up getting sent to the principal's office.

But even there, Henry can't shake his belief in the alien invasion. He tries to convince the principal to sound the alarm and evacuate the school, but the principal thinks he's just being silly.

Finally, as the school day ends, Henry sees his chance to save the world. He spots a strange object in the sky that he's convinced is the alien spaceship. He sets off to stop the aliens from attacking, but realizes too late that it's just a weather balloon.

Disappointed but not defeated, Henry reins in his imagination and returns to his normal life - for now, at least.
