There is too much trash left on the construction site!
Help workers clean it up by jumping on top of the crates that they will throw at you.

Well, sometimes they mess things up and throw a TNT at you.. Oops! Happens I guess. There's a bigger issue as you get higher - birds. Watch out for them!

But worry not because one of your friend came to help you and for a reasonable price he is willing to sell you some tools that will make your job easier and help you make an even bigger tower! How would you like a parachute for example that will save you from a fall once? Sounds good doesn't it? What about a boot (yes, only one) that will make you jump higher? There's a lot of interesting tools!
