In Brocks defense Mudkip can become a ground type if it evolves..
Am I the only one bothered by the fact Ash hasn't aged at all since he left pallet town in Kanto. HE'S TRAVELLED 5 DIFFERENT LEAGUES IN LESS THAN A YEAR. And to make it worse he's yet to do better then top 4 in the pokemon leagues. Averaging top 8.. At least make it to the finals already.
the most dumb thing is that he actually had already travelled over a year sicne there was that 1st anniversary meeting pikachu episode some way back. So Pikachu can grow older but ash can not?
