The Koolboyman Mansion, or Castro Valley mansion, is a building in Castro Valley. It does not appear in Rijon Adventures, as the building was destroyed by a sinkhole before the game's events.

The Koolboyman Mansion is referred to as Mansion on the Town Map. It is a full dungeon complete with wild Pokémon, trainers and items. Exploring it is required to progress, as the player needs to find the Virus Scan on B1F.
Walkthrough[]
The Mansion consists of three floors above ground, and one underground cavern. Like the Cinnabar Mansion in Pokémon Red, Blue, and Yellow versions, it is navigated by activating secret switches, which open and close certain doors. These switches take the form of podiums.
There are two groups of doors, and each time a switch is pressed one group will be open and the other will be closed. On the maps below they are labelled in red and yellow. On B1F, there are obstructing rocks/cliff faces which act in the same way as the doors and are colored accordingly. Using the switches (which on this floor appear as signposts) will make them appear or disappear, revealing either pathways or steps.

On 3F there are three warp panels. The first two (green) will transport the player down to (the green square on) 1F, to a location otherwise inaccessible. From here they must fight the Scientist, but they can then take the stairs to the basement cavern. The third panel (purple) is guarded by another Scientist, and will warp the player back to (the purple square on) 2F. There are also Burglars in the Mansion who walk around like NPCs, and will only battle the player if they are spoken to.
Leaving the Mansion by the rightmost exit on 1F will cause the player to leave by the normal exit, and entering it again will transport them to the normal entrance on the left side. The position of the switches is not reset on leaving and re-entering.
