Here at MandelaEffects.net, we’re constantly on the lookout for curious shifts in memory—especially when it comes to the world of Pokémon, where many of us spent hours learning every name, evolution, and Pokédex entry by heart. And today, we’re spotlighting a bizarre yet strangely familiar memory that many fans insist they clearly remember:
The Memory:
Diglett evolved into a two-headed Pokémon called Dugduo, which then evolved into Dugtrio.
The evolution made perfect sense:
- Diglett = 1 head
- Dugduo = 2 heads
- Dugtrio = 3 heads
This “missing link” evolution of Dugduo seemed so logical, so consistent with the naming structure and evolution pattern, that many fans still swear it existed.
The Reality: Dugduo Has Never Existed
According to every official Pokémon game, anime, trading card, and encyclopedia…
Diglett has always evolved directly into Dugtrio—skipping any two-headed form entirely.
There’s no record of a Pokémon named “Dugduo” in any generation. Nothing in Gen 1. Nothing in spin-offs. Nowhere.
Still, the memory persists—and not just from one or two people. We’ve encountered multiple fans who confidently recall Dugduo as part of Diglett’s evolutionary line.
“I Remember a Two-Headed Diglett!”
Many who report this Mandela Effect say they specifically recall seeing a Diglett-like Pokémon with two heads.
It’s not just a name confusion for most—it’s a visual memory too.
The Doduo Theory
Skeptics claim this is a simple mix-up with Doduo, the two-headed bird Pokémon that evolves into Dodrio.
But here’s the thing:
- Doduo is clearly a bird, while Diglett is a ground-type mole.
- Doduo evolves from itself, not Diglett.
- The name “Dugduo” fits the Diglett/Dugtrio pattern far more closely than “Doduo” ever could.
While it’s possible that a few people misremembered the name, it doesn’t explain the large number of fans who recall a two-headed mole-like Pokémon between Diglett and Dugtrio.
We’re Making This Mandela Effect Official
Because we’ve seen enough people sharing this exact memory, we’re officially labeling Dugduo as a recognized Mandela Effect on MandelaEffects.net.
We’re publishing this post to gather more community input. If you remember Dugduo, or think you saw it somewhere—you’re not alone.
Help Us Dig Deeper
- Did you ever train a Diglett and swear it became Dugduo before Dugtrio?
- Do you remember what Dugduo looked like—sprite, shape, color?
- Did you ever talk about Dugduo with friends or see it in unofficial guides, fake cards, or fan art?
Let us know in the comments. We’d love to include screenshots, old forums, or any residue that supports this mystery.
Because when it comes to the Mandela Effect—every memory matters.
