The first time I came across this particular pokémon I didn't think it was "real." I distinctly remember (because it was two months ago), I was sitting on my brother's couch reviewing his old (i.e., worthless) pokémon trading cards with my four year old nephew. My nephew pulled it out of the stack to show me.
"What's this one, Uncle Willy?" he asked.
"I don't know, I've never seen that one before."
Seriously. I thought it was some kind of aberration. A pokémon that had to have been made up only for the trading card game. I took the time to look this guy up on Bulbapedia and was surprised to see that he had been introduced in Generation II. I had played Pokémon Gold!
The second time I saw this guy was in the anime episode "Some Like it Hot." Really? an entire episode devoted to this most forgettable of pokémon? He's so bad I even forgot he existed at all!? Geez. That episode didn't even have particularly good plot. An oversized one was blocking the path Ash, Brock, and Misty were taking so they needed someone to capture it. There you go.
Oh well - since we are done covering all of the 600+ level competitive pokémon, it's time for a palette cleanser - Magcargo.
