|Prerequisites||Ghost Suit, mask|
|Be A Ghost|
Revenge! was a mission on Spineworld.
Gri-Dun saw a ghost that scared him. He thinks it was a trick from Mr. Tonno and wants to pay him back. Gri-Dun knows that Mr. Tonno is more scared of ghosts than he is and gives a mask to the player to do something with it.
Go to Zorof's Shop in Cloud Garden and combine the ghost costume and the mask in the Zoromorph. A scarier ghost suit will come out. Change into the suit, go back to the Aqua Lounge and scare Mr. Tonno. Change back into normal clothes, go back to Gri-Dun and collect the reward.
