Eat fish quickly to fill your frenzy meter. When your frenzy meter is full, you 
will get double points for each fish eaten. If the frenzy meter is filled twice, 
you will earn a double frenzy bonus. When this happens, you will get triple 
points for each fish eaten. If you eat a 2x bonus bubble during a double frenzy, 
you will get six times the normal point value of the fish.
