Morty is in the Burnt Tower in Ecruteak City. But you have to defeat your rival (who is also in the Burnt Tower), fall down the hole and witness Suicune, Raikou and Entei. From there, go back up the staircase and you will be able to fight Morty.
Get the squirtbottle from the flower shop in Goldenrod, and water Sudowoodo. Then you can walk through the passage to either Ecruteak or Violet.
