If a z-bot doesn't blow the barrels, what does? Not a sphere or boulder 'cos I've tried and the breaktiles stop it. I've always had the green timers operated by a green sphere not a z-bot.
EDIT: I've got further now, but not using your way at the start Bob.
Here's what happens using your way. The white button isn't covered and the barrels aren't blown.
Here's what happens using my way. White button covered, barrels blown.
I'm still working on the timing with the coiley etc. Back later.
DOUBLE DOG EDIT: Yes!!! I did it! Turns out that the timing with the coiley was easy, but the ghost caused me 3 or 4 restarts. It either got trapped on the timer or the ice cube bounced back and killed Stinky!
Then of course there was the red TP conundrum. That took a couple of restarts too.
And the ending!
Thanks for the fun Bob.
PS: I can see from my screenie now that it's possible to cover the white button using your way, but still no idea how you intended to blow the barrels.
