Super Bomberman 2

The levels in this world contain enemies that are hidden inside soft blocks: the soft block must be destroyed before they are unearthed. There are blue mechanical orbs that move back and forth on tracks in some levels. They don't damage Bomberman, but can push him off the edge of a platform if he gets in their way, costing a life. The orbs cannot be bombed, nor can bombs be placed on their tracks.
Most of the levels are split into segments that can be reached via moving platforms. Some moving platforms don't spawn until a secondary switch is activated (they're easily identifiable by their grey colour and blue lights in the formation of an "X"). Staircases also show up, but be careful - the staircase is destroyed is bombed.

ENEMIES: Brain Bomber
Brain Bomber generally follows Bomberman and uses remote-controlled bombs; if Bomberman is in range, they detonate immediately, and if not, they'll detonate after the same length of time as any other bomb. He can only lay one bomb at a time and they have a 1-tile blast radius, so he shouldn't be much of a challenge. Requires 3 hits to defeat.

Stage 4-8

ITEMS: n/a
ENEMIES: Bomber Robo
Bomber Robo (ボンバーロボ) persistently follows Bomberman. When nearby, it will lay a large bomb with a diamond-shaped explosion (about 9 tiles across and five tiles down - see example); it is vulnerable to its own explosions. Requires 9 hits to defeat.

Munchie Jump (パクパジャンプ) Pursues and eats bombs that are within 5 tiles range of it. Will not notices bombs more than 6 tiles away from it.

Blocker (ブロッカー) Moves aimlessly; stops to change direction upon collision with either a wall or another enemy. Will occasionally spawn soft blocks when it stops to turn.

Robodash (ロボダッシュ) Moves randomly, sometimes changing or reversing direction. Requires 2 hits to defeat. Will increase its speed after being bombed once.

Bakuda Red Mk. II (バクダレッドII世) Behaves identically to Bakuda Mk. II: Moves in different directions, stops periodically to detonate itself, during which period it is invincible. It has a 10-tile blast radius and its explosion will penetrate through soft blocks.
