Okay, okay, we're just speculating, but The Pokémon Company's latest Muk-up is a Magnemite oversight that might be worth something some day (h/t Kotaku).
See, it turns out that Magnemite should look like this (helpful red circle added by TPC themselves):
But the plushie looks like this:
You see?! Terrible.
The Pokémon Company wrote an apology on its Japanese site, expressing its "sincere gratitude" to all their customers for their support despite the grave error.
Anyway, if you have one of these plushies, sold through Pokémon Centers, Pokémon Stores, and Amazon Japan, you can just bring it in to your local Pokémon Store for a replacement.
Or - and we're not necessarily encouraging this - you could just keep it. We know very little about toy prices, but aren't defective cuddly toys usually worth something some day? There may be a collector in thirty years who just can't wait to get their hands on a slightly wrong Magnemite plush.
