Bomberman Story

Faster Drops! Aside from that, nothing to see in MtRoad. Move on.

When Zeta is first entered, it's in the middle of a sand storm, preventing you from going anywhere. Use Youno to calm the storm, though there's still a danger of falling, flaming rocks from the sky.
In the second-from-the-right house on top is Tekuji, who gives you the StepCount. Walk 100 steps and return it to him, and you will receive Sibaloon.
There is also a Karabon coliseum.

SararMts has three caves: The lower cave will take you out of the top-right cave. The top-left cave houses a girl who will refill your health.

OldBase's top cave takes you out of the bottom cave: you can reach ground level by going right and taking the staircase in SararMts, and walking right again.
The base contains P.Animal, who's in need of rescue. Time for another mini-game!

If you've played the Spark Bomber mini-game from Bomberman World, you'll be familiar with this. The path of Hige Hige Bandits bobs up and down, and touching them will throw you back to the overworld. Traverse it successfully and P.Animal is yours!
Push the blocks and leave through the bottom of the base.

Quiksand's sands will move you in whatever direction they're facing. There's nothing of note here.

Buy the Teriyaki Beef in the Shop. Once you have Karabon Unagi, return here and stand on the altar to unearth GlmBase at the top right of Volcano.

Desert is a large map, and has several important objectives.
The bottom-left cave will take you to Omega, back in the Field Zone; take the Teriyaki Beef with you. The cave next to this one has a kid who will give you a Large Medicine.
After Golem Bomber is defeated, the staircase in the lower-right will be unearthed and will lead you to Theta - your first step towards reaching Fantasy.
Also after Golem Bomber is defeated, a "Phantom Oasis" will begin appearing on this map randomly. It may take several attempts to find, but entering it will net you Elekong.

LavaPool is little more than a maze of platforms for you to test Sibaloon out on.

Volcano is a massive map, filled with lava, raining rocks, and trenches that will periodically fill up with lava. Be on your guard.
There are a lot of caves on this screen; the caves I have marked blue and green lead to each other; the path between them is what you'll want to follow to reach GlmBase at the top-right. Be aware that unless you have taken Unagi to Ita, GlmBase will not appear.
The cave below the lower blue cave has a girl who, if you give her Teriyaki Beef, will add an extra heart to your metre. Also to be found are two Shops and an Arcade (with a base score of 60).

GlmBase is found in the top-right of Volcano. No point splitting up the map image for an area that offers nothing outside!
