Based on that adventure game idea I had with Parker. I was thinking of it being like Banjo Koozie or Spyro Riptos rage, where you have to learn new skills or obtain new items in order to advance. For Parker, he is initially unable to swim due to being diaper dependent and we all know what happens to diapers in water. Because of this, he first needs to find a waterproof diaper cover before he can do so. He also needs a specialized underwater pistol so he can deal with underwater threats.
