Board notes 5 details
- Layout
- Worry floats in a flooded lab beside a right-side growth machine, while test tubes and a mortar sit above a closed pale-blue cabinet at lower left.
- Goal
- Open the cabinet, enlarge its hidden sponge in the machine's lower chamber, and drain the water until Worry can stand.
- Opening
- Slide the pale-blue cabinet door right to expose the small yellow sponge inside the dark compartment.
- Danger Zone
- Putting Worry into the machine causes a red X; the person silhouette is a temptation, while the absorbent sponge is the useful object.
- Mechanics
- A hidden-object reveal feeds an object-transform machine, whose enlarged output automatically absorbs the environmental hazard.

Put the small yellow sponge from the lower-left cabinet into the machine's bottom chamber.

Slide the pale-blue cabinet door beneath the mortar to the right.
Why does putting Worry in the machine fail?
