General tips to help make this easy: Buy the half off thing from the shop first. Upgrade Nuparu first fully. He is the easiest of them all to destroy a lot of things at once. Use him on the level specified (well unspecified) above, and you will gain as much lego pieces as you let it stand there for. Then buy every upgrade and the bonus levels with your huge amount of legos. Go kill the enemies over and over on the bonus stages to gain your enemy kills. Then go make sure you have gold medals on every level including the bonus stages and you should get 100%. If not, go get the rest of the canisters. I did not have to do this, in fact I still needed canisters from 3 different levels. If it won’t work for you, I got extremely lucky. Anyways, that should cut your time down from getting 100% of the game. Personally this game got old very fast and I fell asleep about 6 different days playing it.
