hehehe level 5 walkthrough
First, grab the red scaffold and jump over the molty. Stand close to the edge of the floor and drop the scaffold. It will now be acting as a plank so you can use it to jump across to the ladder.
When you get to the top of the platform, jump to the left and grab the next ladder. Climb to the next platform and run left again, jumping to the NEXT ladder.
Climb all the way to the top of the level and go right. Be careful of the 2 molties under the floor because they shoot fire up to your level. Careful timing should get you through unharmed.
Drop down the right side and you will land by 3 crates. Grab each crate and drop them down to the lower platform in the middle of the level.
Drop down to where the crates are and stack them all in-line with the ladder. Use the crates to get jump up to the bonus bottle.
Next, drop the crates down the right side then jump down with them. Keep dropping the crates until they are at th every bottom of the level being careful not to hit the molty (he will break the crate and you will need to go all the way up again to get a new one).
When all the crates are at the bottom you will need to stack them up under the middle platform while avoiding the molty.
Once you ave them stacked you can grab the red scaffold again and jump up the crates onto the middle platform. Walk to the left and the molties will walk onto the scaffold. You can then walk to the right and let them off on the next platform. You should be able to transport 2 molties at a time with no problem. Once they are on the right platform, set the scaffold down and use it to jump over to the left platform.
Now you can get they key and carefully jump down to the door.
I've got this off a walkthrough thing =]
