Mudkip has an error, mudkip says that his type is water and ground (in the original games it is only water ) and PRO when i use a move water like surf, the message says that the movesurf is not very effective (that is good if mudkip is water type, but it is ground also, and it convert the move surf in a move type normal for mudkip )

 

I believe that mudkip should not have the type ground in the pokedex, and in its date

fixed in next version to come.
