Attention Monster High fans, this is not a drill. Katseye, the global ghoul group sensation, just dropped a screaming new video of the original Monster High theme song!

The official fright song and video premiered Thursday night at 9 PM PT / 12 AM ET on the Monster High YouTube channel.

Katseye are now proud alumni of the creepiest school around—Monster High!

In the video, each member transforms into a unique monster: Megan becomes “The Húli Jīng,” Lara channels “The Rakshasa,” Sophia flies as “The Manananggal,” Manon dives in as “The Sea Monster,” Yooncha haunts as “The Jangsanbeom,” and Daniela howls as “The Werewolf.”

Each ghoul represents a monster from global folklore, reflecting both Monster High’s and Katseye’s international appeal.

Their monster makeovers serve as a powerful nod to the diverse and spooky stories found across cultures, a true celebration of global girl power.

Mattel Creations teased the video earlier in the evening with a cryptic Magic 8 Ball that revealed a crown, key, cherry, anchor, shield, and shell—alongside the message:
“👑🗝️🍒⚓️🛡️🐚 – and that’s ALL you’re getting out of us… for now 🤭.”

Within just one hour, the video racked up over 5,000 views.

Now our curiosity is officially piqued. Is this part of a new Monster High series or movie? Will Katseye get their own Monster High dolls? We’re dying to know.

In the meantime, we’ll be playing the anthem on repeat.
