|BERLY'S LOST BALL|
VAN asks OMORI and his friends for help because he accidentally knocked BERLY'S BALL somewhere deep within the VAST FOREST. BERLY will accompany the group on their search for the LOST BALL. You cannot leave the VAST FOREST while BERLY is with you. You need to have BERLY with you to finish the Quest.
To find the LOST BALL, the player has to simply walk one room south of the FOREST PLAYGROUND, then continue moving west in the lower paths of West area. Doing so leads the group to a detour with a LOST SPROUT MOLE and a bridge. Cross the bridge and you'll find BERLY's LOST BALL right below a bench.
Once BERLY retrieves her LOST BALL, the group can head back to the FOREST PLAYGROUND to complete the quest.
After returning to the FOREST PLAYGROUND, BERLY will thank the group for helping her find her LOST BALL. She will also tell them to come see her before leaving once again. From that point on, BERLY will teach AUBREY the HEADBUTT skill and gives her a BUTT CERTIFICATE as a token of gratitude.
Otherwise, if the group doesn't have this item upon their first visit to OTHERWORLD, then the achievement cannot be obtained.
