The centaur one reminds me of this cartoon I saw once. A doctor was talking with a half capybara/half human (human torso and lower body of capybara), who is anxiously waiting to see his child. The mother of said child is a mermaid, and the doctor is cautioning the father, who interrupts the doctor and says, "yes, I know he could be completely human, just show me my child." The doctor then shows the guy a child with the body of a capybara and a fish head.
Other than that, I just want to know what the jellyfish launcher button actually is.
