What are these glass removers you speak of???
I had been trying and trying 345 constantly thinking "I wish there was a pal that broke the glass..." so I was surprised to read in this thread that some of you were talking about using glass removers. Checked the collections - and there they were in the new Castle Clan (Ballin, Baxter etc) ! As I'm not the type to try for 2 or 3 stars when I get through a level (as per my previous post - I had barely got 3 stars throughout Castle Markets,) I thought, OK, I'm going back to try to earn a new pal. Yes I got a Castle Clan pal, no it was not a glass remover pal (Lorien - Light blue lanterns.) Sheesh.
So with the advice shared on these posts, I kept trying with 345 and eventually got through. It was with the blue and yellow line blasters, plus the purple lantern light plus Phoebe (red block + line blaster.) I had used this line-up a few times before and it hadn't worked, so it took me perseverance and luck. (Supported by some great advice on this thread!)
I'm really looking forward to getting some of those Castle Clan glass removers.
Thanks to all for your invaluable advice on here!
