- Dana's backstory shows us she never had any interest in becoming the next Wonderella like her mom - and even though she enjoys the perks of being Wonderella, her half-assery at the job makes sense  
- In Dr. Shark's first appearance, he tells us that he was trying to use shark stem cells to cure cancer. The brilliance comes in when you remember that sharks are known for their excellent immune systems, and are one of the few species that are believed not to get cancer (which is false in real life, but makes perfect sense here). So using shark stem cells might not be so random.
