The Cactus is a variety of plant that appears in two of the Cube Escape games. They are desert-dwelling plants famous for their spine covered bodies, though both appearances in the series have domestic pots.
Cube Escape: Seasons[]
The Cactus is seen in all four seasons, though it can only be found once the player travels back from Winter. When in Spring, using the code learned in Summer, a cactus seed can be taken from the locked safe and planted in a pot previously taken by a flower. It will then grow in each subsequent season, until finally giving fruit when the player returns to Winter. The fruit can then be taken and blended, to power the nearby machine.
Cube Escape: Case 23[]
A cactus appears in the Murder Scene, on the top of a cabinet. It shares its pot with a identifying card reading 'Neobuxbaumia', a specific genus of cacti. The sign is used to solve a crossword clue, but the cactus itself has no real use.
Given that the Room and the Murder Scene are part of the same house, it is possible for the cactus seen here to be the same cactus seen in Seasons, as it has the same appearance as the Cactus when seen in the Fall, including the same pot. If this is the case, it is not clear how or when it moves from the Murder Scene back to the Room.
