Go to goldenrod city then beat Whitney in the goldenrod gym then go to the flower house and get the squirtbottle then walk to route 36 and use the squirtbottle on sudowoodo and then either defeat sudowoodo or try to catch it with your balls[If you are lucky]
I assume you are talking about the spray bottle to awaken Sudowoodo, and in order to do that, you must first beat Whitney, then go up to Sudowoodo from the Goldenrod City side, talk to the girl that is interested in Sudowoodo. She will go back to Goldenrod. Follow her back to her house, which is east of the gym, and talk to her sister or mother or whatever and she will give it to you.
You have to go back into the Goldenrod Flower Shop and talk to the lady at the front desk and she will give you a Squirtbottle and then go back to the Sudowoodo tree and click it and it will ask you if you want to spray it and then click yes and then it will attack you in a battle.
Go back to golden rod city and go to the flower shop by the gym, she will give you a squirtle squirt bottle , go back to the sudowoodo and spray him, then the inner feline in him breaks free and he battles you

Near Goldenrod, there should be a 'strange tree' or something similar to that blocking your path. Defeat the Goldenrod gym leader, get the badge, then go to the Goldenrod Flower Shop. There, the lady will give a squirt bottle. Return to the 'strange tree' and spray it. The 'tree' will move, and attack. It should be a sudowoodo, if I'm not mistaken.On the route west of violet city
first you go on the route that has the strange tree and spray it with the squirt bottle and it will attack you and use a fast ball to catch it and there you go a sudowoodo
Go to the flower shop next door. Talk to the lady she will give you a spray-gun for the dancing sudowoodo on the way to Ecutreak City.
