Useful Charms for 3 Stars tipsed by Sebastian Ramirez: Charm of Insurance, Charm of Webbing, Charm of Fortune Spiders, Charm of Scrolling, Charm of Shielded Spiders
I have been used to get the Magic Potion 3 extra holes in the ceiling for almost any level, but for level 141 it is not a good idea at all! The Bombs near the ceiling will go off after unlocking the chain, if there is a hole in the ceiling near them! So DO NOT use the +3 holes in the ceiling Potion!!!
I found out an easy spot to remember for aiming safely at the left side locked bubble. You place your mouse pointer at the lower cross point for the twig and the pole in the background. Never fails!
Please watch these video walkthroughs by Sebastian Ramirez to get additional hints on level 141. The Upper video is a really skilled game for almost 3 Stars, without Charms, the second one makes the level look really, really easy, where he does 3 Stars with a little help of Charms.
