Jailbreak Tunnel

Jailbreak Tunnel is a dungeon introduced in PMU 7 that is near the Jail in Exbel. It's the first dungeon to offer steel and dark-type Pokémon. There are 12 floors in this dungeon, with mini-bosses on floors 3, 6, 9, and 12.

The Pokémon in this dungeon are mainly in the level range of 8-16.

Scenery
There are two types of scenery within Jailbreak Tunnel. The first half is elongated and the ground is a gray color, with skulls scattered around and a blackish color. The other half turns more cobblestone grey with grey walls, but keeps the same skulls around. Floors 3, 6, 9, and 12 have a second set of stairs that are brown that will lead to four different mini-boss rooms, each representing a cell with stone tiles on the ground. The final room returns back to the blackish coloring of the first half with two side arches.

Pokemon
The Pokémon in this dungeon are a dark themed variety with the typing being different for most of them. All the Pokémon that are found here are first evolutions (with the exception of Aggron). The Pokémon in this dungeon are low levels, with most being around level 15. An Aggron will appear on Floors 3, 6, 9, and 12, each time with some dialogue. Aggron is Level 18.
