This is just for the people that don't know what to do for the new scenes or encounter the Oddish bug.
First, if you haven't already, keep leveling Zulbat until it evolves into Golbat. You can speed this up by using the Rare candy that level the Punkmon up.
Second, in Cerulean city, choose Gym and Hang out with Misty. Do this FOUR times to see all the scenes.
Third, while still in Cerulean city, choose "explore" it will open a new path to the north; Route 24
Lastly, keep fighting in Route 24 until you run into Oddish. Now if you notice, every single attack you try on it will result in a error, if you choose "ignore" it just shows Oddish doing a move that slows your Punkmon down. It is an forever loop. HOWEVER, you can skip the fight entirely and capture Oddish with a single Ultra ball. After that just name the little guy and enjoy his scenes. He only has three scenes.
