Mirage Tower

2 Pokémon can be caught at Mirage Tower in Hoenn — highlighted on the map below.

Mirage Tower appears and vanishes in the Route 111 desert as the player comes and goes, and exists only in Pokémon Emerald. Wild Sandshrew and Trapinch inhabit its four floors, and climbing to the top, which requires a Mach Bike and Rock Smash, yields a choice between a Root Fossil and a Claw Fossil.
