Sea Puppies is a pet simulator with lots of choose-your-own-adventure aspects. Your goal is to take care of adorable mermaid/doggy sea creatures called Sea Puppies. You raise them, feed them, and teach them lessons about life and what-not, so they become good sea citizens and contributing members of marine society.
Eventually, Sea Puppies will grow and mature, and when they're old enough, will leave you to find their place in life. When they do, they may leave you with souvenirs - to help you remember them by.
