Blubbo: What are they doing?
Momo the Glutton: Getting ready for birthday party! They are always having birthday party!
Blubbo: Ooooh, let's have a bithday party too! Blubbo wants birthday party!
Momo the Glutton: Impossible, bubblehead!
Blubbo: B-b-b-but why?
Momo the Glutton: Because Blubs have no birthday! You have to have birthday to have birthday party!
Blubbo: Why Blubs have no birthday?
Momo the Glutton: Because Blubs were never born. You have to be born to have a birthday, bubblehead! Besides, who'd ever invite a Blub to a birthday party? You're ugly, bumbling, useless creatures who don't even taste good! If you didn't have such a disgusting taste Momo would have eaten you long ago.
