Get killed by the same enemy a mere three times in a row, and the impatient game decides that you need help. And yes, this is the same franchise that once made you figure out that you needed to lug an owl around in your pants in order to solve a puzzle.

Enjoy looking like the mascot for a bad family chicken restaurant, champ."
"Kick your dinner plans into Chicken Gear!"
The hat itself seems disappointed by the player's ineptitude, and, apparently, it's turned to smoking pot to cope with its emotions. You have to look right into its eyes throughout every cutscene that's supposed to be serious, but end up completely ruined by the intrusion of a cartoon chicken headpiece. Come on, some people just want to enjoy the story. That's like making moviegoers wear dunce caps if they fail preshow trivia about the prequel.
