Okay, so “Harry Potter and The Grinch 2” is not an actual movie (sadly… because that crossover would be bonkers in the best way).
BUT if you want a story description, I can totally spin you something fun. Here’s one possible version of what that wild mash-up could look like:
Harry Potter and The Grinch 2 — Totally Made-Up Plot Summary
So picture this: it’s been a few years since the Battle of Hogwarts. Harry’s trying to live a chill life, raising kids, doing dad things, occasionally stopping magical disasters before breakfast. Classic.
Meanwhile, far away in Whoville, the Grinch has been living his reformed, post–heart-growth life. Holidays are peaceful… until weird magical stuff starts happening on Mount Crumpit: ornaments floating, Whos losing their voices, candy canes melting into goo, and the sky doing that ominous green-and-purple swirl that basically screams “someone opened the wrong portal.”
Turns out: a tear between the Wizarding World and Whoville has opened, because some leftover Dark magic from Voldemort finally leaked somewhere strange… and that “somewhere” happened to be the Grinch’s cave.
The Grinch, already dramatic by nature, decides he’s done with creepy sparkly chaos messing with his personal space. So he hires Max as emotional support and stomps right through the portal—which dumps him smack in Diagon Alley.
Cue absolute confusion.
Harry meets him, tries to make sense of a furry green guy yelling about cosmic glitter destroying his mountain. Hermione (who absolutely does NOT have time for dimensional anomalies today) discovers that Voldemort’s old experiments created an unstable magical creature feeding off holiday energy. And guess where it’s heading next?
Whoville.
So Harry, Hermione, Ron, and the Grinch team up. The Grinch’s Christmas-theft knowledge weirdly becomes crucial—because the creature hides inside Christmas cheer and feeds on it like a sparkly parasite.
There’s wand-waving, sleigh-riding, Max saving the day at least twice, and the Grinch complaining the entire time (“I did not sign up for wizards with bad haircuts flinging sparks at me!”).
In the end, Harry helps the Grinch tap into that big now-three-sizes-too-big heart magic, which turns out to be the only energy strong enough to seal the portal and neutralize the creature.
Whoville is safe. The wizard trio gets a new absurd story no one will believe. And the Grinch returns home with a wand Hermione gave him “for emergencies,” which he absolutely uses to summon snacks.
