Reach the west rooms
Cross the Courtyard and deal with the attacking Flytraps, then take the Plant Nursery route into the Rumpus Room. Clear the hiding ghosts and use the dollhouse reflection to identify the shaking hiding place. Circling the large doll counterclockwise unscrews its head and releases an emerald. Continue through the Family Room to the Solarium and pull the cord to expose the stairs. Restore the missing chest on the Solarium table for another emerald; this is not a separate outdoor garden.
Find both keys on the way to the roof
In the West Bedroom, turn the ceiling fan to move the beds and expose the Hiders. Pull the blankets and clear the encounter for the key. Continue by the Crow’s Nest and use the Conservatory’s Bulbs to reach its upper route. The hidden door on the right balcony leads to a timed coin challenge containing an emerald; it is available during B-4. Use Dark-Light on the key painting where the route leads back through the Crow’s Nest, then unlock the West Bathroom. Clear the Creeper encounter and pull the toilet paper for its gem.
Inspect the Rooftop Pool
Use the bathroom chair route to reach the rooftop pool. Reveal the missing frog statue with Dark-Light, then catch the Sneakers to obtain the special key. Polterpup steals it before you can finish the delivery, leading into the next mission. For this mission’s Boo, return to the Family Room and restore the missing painting. On the Skybridge, pull the rightmost hanging flower after its downward strike to release an emerald.
