Week Clue
2 "Hey, young whippersnappers. Reflecting on my long life, I can't believe the troublemaking fool I was as a youngster always acting out to get all eyes on me. Until a teacher pulled me aside after class and made me see I was smarter than the character I was playing. I decided to put the "I" in Einstein, and became a star pupil. I'm still working on shaking my bad reputation. So when this old monster takes his mask off, I hope you're not afraid of who I was a long time ago."
4 "I've always hated the sound of my singing voice, but being Grandpa Monster, it's given me a new kind of confidence. I haven't felt this free since the time I was stranded myself in the wilds, cast away, just to see if I could survive. Left without food, water, and shelter, I mean, I was terrified. With little wild creatures everywhere. It definitely was a challenge, but I made it out by the skin of my three teeth. And now I'm here to take another challenge, securing that Golden mask. I know I'm up against some stiff competition, but I've traveled the world and sold out arenas. Not even that pesky Piglet could stand in my way. Because when I talk the talk, I walk the walk, baby."
