All you have to do with that machine boss level is bounce around and avoid the bullets it throws out. Try to kill the penguins but avoid the orange things that bring out fire. Once the drill has smashed itself into the wall a few times the level is over.
With the bonus level, you don't need to jump on everything to get to the token. When you jump on the ledge where the ladder is you will notice a flying ledge that goes back and forwards. Jump on that and it will take you to the token.
So what do you think of the game? I actually like it but it's hard to find all the tokens. Don't know if I can finish the game without all the tokens but I guess I'll soon find out.

You don't need to destroy the drill - it destroys itself. You just need to destroy the penguins and the other fire shooting things.

Have you hit the target on the track with the cereal gun yet? Do that and the track will stop so you can go either direction.
I don't exactly know where you are so can't help you much.
This level is really confusing as there are a lot of different ways to go so just keep running around and you'll get there.
