The Zombie Bubble course is getting harder, but just rely on your skills you've had thus far, and you will no doubt succeed. The zombie bubble makers have been extra mean in this game, giving you two faux ceilings that may make you think you're at the bubble end, but you're not! At least not yet! Those lines of headstone bubbles are difficult to get around, but just work around them slowly, releasing them one by one to the ground. Once you get a bit further into the game, those maltov cocktails could help you become victorious over this bubble game level!
