Ben 10 can't be the same adventurer guy that once was and I think this is happening for a reason. He can't breath the way he did before, so he has to go to see a doctor immediately. He will definitely feel better after this visit and if you'd like, you can treat him yourself. Play this game and use every tool you have at your disposal to clear and heal his nose. He will definitely be grateful and who knows? Maybe he will take you with him in his next adventure. Enjoy!
