u go to the opposite side of fruit and theres rocks and invisble thingys u can jump on. after u finish the parkour, u see a riddle on the wall and then u jump into a dark blue hole behind it. then u look down to see the fish
theres cracks in the wall telling u to go left or right. the pattern (including the rocks u can see) is right left right left left right left left
