Hey, what do you think this it? It's a real unusual painting... It kind of looks like there's an indention here...
I wonder if you're supposed to insert something...
Come to think of it, there's a door with a large keyhole somewhere in this building. I wonder if this has anything to do with that...

—Baccus resident

18.png Painting of a Big Key? (大きなカギの絵?, Ooki na Kagi no Kai?) is an event from Tomba!. In this event, Tomba must collect several key pieces found in the different rooms of the Haunted Mansion.


Fill the painting with the missing pieces in order to obtain the Big Key.


On the north side of the Haunted Mansion, talk to the Baccus resident inside the room with a door above the save point there to activate the event.

Now Tomba must find the five missing pieces in order to restore the painting and get the big key. Each piece has a number, but they can be obtained in any order.

Head back to the room where the event started and select the pieces from the Item Screen to place them into the painting on the wall. Once all pieces are on the painting, the event is cleared and Tomba receives the Big Key.
