I'm sorry, but out of all the English-language names of Pokemon, Conkeldurr has to be up there with the worst... right? Buibapedia gave me some crappy reasoning behind the name, but I ain't buying it. It's as if Game Freak managed to create an actual version of The Incredible Hulk and have its sole role as a Game Freak employee be to name this one Pokemon. If I'm being completely honest, its horrible name is probably the reason why I never even considered obtaining one for myself in Black version. Added to this that its fugly and slow, and it was DOA in my estimations, unfortunately.
Not that I particularly love Seismitoad (or, as I'm now going to call it - thanks to Syd - Herpestoad) or anything... but it's a Water critter, which is certainly money in the bank, as far as I'm concerned. And at least Seismitoad makes sense as a name.
