I have tried and tried but can not find the 3rd treasure in chest in level 7!
When your at the botomless pit, grab that barrel rocket that makes you fly to the right. Instead, jump left and you'll hit the wall and be falling down. The barrel rocket will start and make it head upwards. There you hold on the spear and jump to reach the treasure chest..
I also had trouble with this until I accidently jumped down with the barrel rocket and went up. I never knew the 3rd treasure chest was there
