TM36 Sludge Bomb

==Information==
Location: Tourmaline Desert
Available: After Badge 14
==Guide==
Take the train to the desert. Go slightly right from the station and go up until you reach a new rail, you can check whether the Mirage Tower Indicator Pole appears. If the Pole appears, the Mirage Tower appears. To get this item, you need the Mirage Tower to NOT appear.
The left image shows the area when the Mirage Tower doesn't appear. The right image shows the same area when the Mirage Tower does.
If it appears, touch one of the Light Shards at the oases to make it disappear. There are four oases near the arrival station. The two on the first row are to the left of the station, and the two on the second row are to the right.
Once the Indicator Pole disappears, go all the way to the top right corner of the desert where the Mirage Tower is.
