First of all, I'm sorry.
Answer:
1. "First step."
Ok, when you go across the trampoline then collect the lower two
bonuses coins next to you, then use the transporter to collect the key.
2. "Destroy the metal box".
Destroy the box. How may you ask?
Using the boulder, roll it on the ice, then when it comes back push the
metal box up just when its moving on that space.
(You can collect all the bonuses now.)
3. "Glitch starts here".
This will take some luck, move the boulder up JUST before a metal
box lands on the water.
4. "The result".
If you look to the left, you should see a transporter randomly going up!
Then go into the teleport and you will be teleported the other way.
Alot of people probably got stuck on this one.....
