My most favorite Pokemon in Hoenn is Zigzagoon! Just love it's cute raccoon design (many times I don't want to evolve mine) - but I love Linoone a lot more. I also like Skitty, Delcatty, and Zangoose (I also like Poochyena & Mightyena) -
specifically in Hoenn: I prefer weasels and cats over dragons and legendary (in Hoenn, none of the legendaries where based on weasels or felines).
