Beelsteambub

 is the boss of Last Stop: Hall of the Hobo King. It is a horrifying abomination: A sentient, aggressive steam locomotive.

Attacks
The Beelsteambub is one of the most frustrating bosses if you aim to achieve all the goals. His most devastating attack is the fire breath, which floods a cone-shaped area with flames, knocking your hero back and setting them on fire. Another is launching fireballs from its exhaust which hit a fairly large area. He can also deliver a devastating attack by rising out and falling on your hero (and, of course, that's the only moment when he's vulnerable).

Oh, did we also mention zombies and falling rocks?

Tactics
Frustration is the name of the game. It's best to break the tactics down by attacks.


 * 1) His flame breath is devastating, but he only attacks three pre-set locations. Assuming the arena is 180 degrees with the Bub at the center, each 60 degree angle is a potential attack area. Skirting the edges between two areas will allow you to lure his attack into one, as he picks the one where your hero is in when he starts to prepare for the attack.
 * 2) His fireball attack is easy to dodge, as the target area is illuminated. Move away before he hits. Lather, rinse, repeat.
 * 3) His smackdown is devastating and fairly difficult to dodge, as you have a second or so to move out of the way. However, dodging the attack will allow you to attack the Bub and actually deal damage.

The most frustrating aspect are rocks. Getting hit by one fails the hidden objective, but you can easily reset the counter just by getting killed and loading a checkpoint. Just keep trying and disregard the rocks on subsequent playthroughs.
