Update: I was unfortunately not aware of Shamus Young's severe criticism of Fallout 3 available here to link in the original piece and I regret that. It dovetails rather nicely with what I've written and it's much better executed than my piece. I strongly recommend anyone...
How to not go through attacking more blobs
1. Go on top of the ship where you save Gus's house. It in on the thinnerfall
2. Where in the arena you dont have to do it!
This easy trick will allow you to trap enemies like the Beetleworks (the bird things n the ones who throw paint and thinner at you) and the Robot Pirates. First You'll have to lure the enemy to a spot where you can thin things out, thin it out, then re-paint it as fast as You can. If you did everything right, enemy will be trapped, and won't be able to move or attack. Unfortunately, when You die for whatever reason, they'll be free again.

Disney Epic Mickey Hints
Gilda's Lost Axe quest glitch
When you first arrive at Mean Street, talk to Gilda, the cow lady who is located in front of the Fire Station. You will need to talk to her multiple times in order to begin the quest. If you recover the axe in the "Slopes" area during your ascent up the mountain you willl ned to thin out the giant Oswald face when you reach Oswald's lair to reach a hidden room. When you come to the end of the corridor in this room, you'll find some large, unthinnable metal bars, and Gus will offer you the opportunity to use Gilda's axe here to explore this area further; don't do this. Instead return it to Gilda and upon returning to OsTown. When you return to the Mountain later in the game, thin out the Oswald face again and go back to the bars. Gus will still think you have the axe, and you'll be able to use it to pry your way in and explore! You'll now be able to reap the rewards of both the "hero" and "scrapper" outcomes of this quest, while it will be officially recorded in your quest log as having gone the "hero" route.
Walt Disney's Appartment
In order to unlock the window above the Fire Station leading to Walt Disney's apartment, you must beat The Lonesome Manner and return to Mean Street. Talk to the Gremlin at the Penny arcade and he'll tell you theres another function of the machine, but he needs 30 Power Sparks to work it. Collect whatever remaining power sparks you need and give them to him. He'll tell you something has activated at the fire station. Jump up to the window above the door there, and Gus will ask if you want to enter. Inside are two gold E-Tickets with Oswald on them instead of the Mickey Mouse logo. They are worth 150 Tickets. Note: The Oswald Tickets, unlike the normal E-Tickets around the park, will not reappear.
