Why You Can’t Find the Glasses Even When Itemfinder Is Shaking Wildly (Route 116 – Pokémon Emerald)
Short Answer
Stand next to the spot where the Itemfinder is shaking wildly and interact while facing it.
Situation
On Route 116, you meet a man who says he dropped his glasses and asks for help.
You try using the Itemfinder, and it clearly reacts — sometimes even “shaking wildly.” Your character turns toward a direction, and it feels like you’ve found the exact spot.
But even when you stand right on that tile, nothing appears. There’s no visible item, no sparkle, and interacting there doesn’t seem to do anything.
It starts to feel like you’re doing the right thing, but the game isn’t responding.

Solution / Place
If the Itemfinder is shaking wildly, you’re already on the correct spot.
The glasses are a hidden item on the ground.
When the Itemfinder reacts strongly, it points to the tile where the item is placed but you won’t be able to pick it up by standing on it. You need to be next to that tile and interact toward it.
In Short
If the Itemfinder is shaking wildly, stand beside that spot and interact while facing it.
