Passho

Passho is a type of Berry that can be planted in the Farm. It can be obtained by surrounding an empty plot with at least 1 Oran, at least 1 Chesto, at least 1 Kelpsy and at least 1 Coba.

When a Passho berry is not surrounded by at least one other berry, there is a chance it may mutate to a Yache. On obtaining your first Passho berry, plant a berry (Kasib is a good choice) around it to avoid it unintentionally mutating and then needing to reobtain it.
