Nostalgia has a funny way of filtering out the weird parts of our favorite shows. However, when you rewatch some childhood classics, certain characters feel less lovable and more disturbing. Here are 15 kids’ TV personalities who, in hindsight, were way creepier than we gave them credit for.
1. Big Baby (from Toy Story 3)

With one blinking eye and a slow, lumbering walk, Big Baby was a nightmare fuel in doll form. It didn’t help that he was completely silent. Even though he had a tragic backstory, his blank stare gave major haunted toy vibes.
2. The Groke (from Moomins)

She glided silently, froze everything in her path, and never smiled. The Groke’s ghostly presence made her feel more like a horror villain than a children’s character.
3. Nosy Neighbor (from Courage the Cowardly Dog)

Every random character in this show felt off, but the nosy, wide-eyed strangers who wandered into Courage’s life took the cake. Their odd behavior and exaggerated expressions made them unsettling to watch.
4. Krumm (from Aaahh!!! Real Monsters)

Holding his eyeballs in his hands was just the start — Krumm’s whole vibe was grotesque. His breath, armpits, and voice were all part of his monster charm.
5. H.R. Pufnstuf (from H.R. Pufnstuf)

That giant dragon costume with blinking eyes and slow movements felt more like something from a fever dream. His voice and awkward gait didn’t help either.
6. Baby Sinclair (from Dinosaurs)

At first, he was adorable with his catchphrases and big eyes. However, the constant head-bashing, screaming, and chaotic energy got intense fast.
7. The Yip Yips (from Sesame Street)

They dropped in from space, made strange sounds, and stared without blinking. These alien puppets felt less educational and more like an alien invasion.
8. Boohbahs (from Boohbah)

Fuzzy, silent, and oddly hypnotic, these rainbow blobs moved in slow, eerie patterns. They were designed for preschoolers, but with a vibe that screamed experimental horror short.
9. Baron Silas Greenback (from Danger Mouse)

That raspy voice, hunched posture, and constant scheming gave this frog villain serious nightmare potential. He was supposed to be a cartoon baddie, but something about him just felt off.
10. The Puppet Segments (from Mr. Rogers’ Neighborhood)

The soft, slow voices and minimal animation of the Land of Make-Believe puppets could turn creepy fast. King Friday, in particular, had an unsettling stare and a commanding tone.
11. Gak the Slime Monster (Nick Commercials)

This neon goo had a life of its own and made gross noises that were way too realistic. Kids loved it, but the sentient slime idea feels weird now.
12. Binyah Binyah Polliwog (from Gullah Gullah Island)
Toho Scope on Flickr
He was meant to be friendly, but his huge eyes, exaggerated movements, and deep voice could feel jarring. The costume looked like something out of a theme park fever dream.
13. Slappy the Dummy (from Goosebumps)

With his evil grin and lifelike eyes, Slappy was a walking (and talking) childhood trauma. He had a creepy voice and a penchant for causing chaos.
14. Plankton (from SpongeBob SquarePants)

At first, Plankton seemed like a harmless villain. However, his constant surveillance, obsession with control, and unblinking eye turned him into a low-key stalker.
15. The Red Guy (from Cow and Chicken)

A naked devil with no pants who yelled constantly? Yeah, that’s pretty creepy. His exaggerated expressions, disturbing humor, and tendency to appear out of nowhere made him feel more unsettling than funny.
