The event can be activated in two ways:
- When Tomba speaks to the Donglin inside the hut connecting the Laughing Crying Forest to the Deep Forest
- When one of the three wooden poles connected to a boulder in the Laughing Crying Forest is struck with the Hammer or Fire Hammer.
In order to clear the event, all three poles must be struck to destroy the boulder and reveal a blue treasure chest hidden inside. Once the treasure chest is opened and the Grapple inside is collected, the event is cleared.
