After spending an entire train journey home sketching the thing, I'm going to have to say that Beadaru (or whatever the hell it's name is) has now become my favourite 4th generation water pokémon. It's that scruffy looking face with those blank, psychotic eyes that have drawn me to it. It's not the same sort of mindless stare of stupidity that Psyduck and Slowbro weild. No, this guy's eyes are filled with nothing but pure insanity. And really, isn't this the sort of thing we look for in a pokémon?
Also, he reminds me a lot of Boss Beaver of Timon & Pumbaa fame. Man, Boss Beaver was an awesome character...
Buoysel is still pretty high on my favourites list, and the Pochama line also gets a thumbs up.
