There are many threads about this level (so it must be a real doozy) and most of them are about the ice, or the button maze, or the reflectors. So, I guess that makes me the really stupid one here.
Because for the life of me I CANNOT GET STINKY'S PART! What am I supposed to do with the steel box? I assume the goal is to get rid of it, but how?
Stinker Rescue (surprise, surprise)
Push it through the red transporter and follow it through. Walk down over the first conveyer and go to the right through the wall up and left. Push the box back through the red transporter. Push the box over the ice and across the ice between the stinker and the green transporter. Follow the box across this ice. Push the box down and then to the left onto the conveyer belt. Now the box should be circling on the ice. Go back to the green transporter. When the steel box goes past the conveyer on the ice, wait a half a second and go through the green transporter. The box will bounce you upwards and you will save the stinker. I hope this helps!
I hate fake walls too. To tell you the truth, I knew about them but didn't put two and two together. The big problem with the level is that I'm not sure what I need to do. Usually, once I know the goal, figuring out how to accomplish it is often easy-peazy.Don't worry, CRJ. Someone very kind helped me here too. I really hate fake walls. Guess I just didn't try enough.

For instance, that box blocking the stinker in Peegue's section: does it need to be destroyed or does Qookie and the rest switch off the conveyer at some point? And did I correctly read somewhere that the UFO does not need to be destroyed?

And just for the record, are there any Chompers hidden anywhere? That's the other thing I hate about fake walls; those nyack-ing teeth just LOVE hiding in fake walls.

You need to destroy that box. The timer stops ONLY the conveyor which frees Peegue.
You DO need to destroy the UFO, otherwise you won't be able to save the stinker near the UFO.

Rest in peace, Kym. I hardly knew ya.
Rest in peace, Marinus. A bright star, you were ahead of me on my own tracks of thought. I miss you.
