I actually have 3, I'm terrible at making decisions.
Anyways, these 3 are my favorite. Meganium's name is one of the better word amalgamations when it comes to Pokemon [Mega+Geranium, for those that don't know] and is definitely a creative one as well, given that Meganium isn't directly based on any one animal, so they couldn't slap something like 'Flauropod' or 'Rabbush' on it. I like Buizel's name for the same reasons as I like Meganium; it's simply another creative word combination that was pulled off extremely well, especially in the subtle spelling, which doesn't directly include 'buoy' or 'weasel and also make it's name look better aesthetically. Finally, Electivire is just fun to say, really, I remember when I was much younger and watched Electivire appear in the anime for the first time, and remembering how cool the name was, the 'v' in place of the 'w' in wire really helps it sound better, although having two v's and having it named Electivvire would be even more creative, given that two consecutive v's look like a 'w'.
