The 4-in-1 Plant is a Docking Station agent created by Ghosthande. The plant may take the form of one of four species of bromeliad depending on the environment in which it sprouts. Each variety sprouts from and later produces the same kind of seed, which is capable of growing any of the four kinds of plant--hence the agent's name.
Not to be confused with the 5 in 1 tree, which is a completely different agent.
