Yakkey

"Heeeeeeelp! Master Tubba Blubbaaaa!! A thieeeeeeef!!!"

- Yakkey



Yakkey (referred to as Mystical Key as an item) is a talking key in Paper Mario. Yakkey's name is a portmanteau of "yak", which means to talk non-stop, and "key". It is needed to open the door to Windy Mill. The key is locked away in a treasure chest in Tubba Blubba's bedroom.

Mario has to sneak past Tubba Blubba, who is sound asleep in his bed, and open the treasure chest containing Yakkey. However, Yakkey is a talking key who is completely loyal to Tubba Blubba. As a result, Yakkey screams as loud as he can, causing the "invincible" Tubba Blubba to wake up. Mario runs away with the key, and Tubba Blubba chases him through his fortress. Eventually, Mario reaches the windmill that holds Tubba Blubba's weakness, his heart. He uses the key to open the mill, and defeats Tubba Blubba's Heart deep below. Later in the game, Yakkey can be found by the well in the Windy Mill desiring to guard a new secret, hopefully a happy secret such as a present.

Tattle
Goombario can use Tattle on Yakkey when Mario finds him by the well inside Windy Mill.
 * This is Yakkey, a magical key. It was lucky for us that it spilled the beans about Tubba Blubba's secret. But I wonder what it's going to do...
