As always use the "other" tips available on the blog ...
Here your 1st priority is to lose the bombs,
but keep an eye out for any good specials / combos as these
are the ONLY things that will get the jelly
in the four "island" cells.
After the bombs, clear some of the centre to allow room to
make better specials - 4/5 ones ...
But ultimately you just need
either a basic horizontal line blast or, better, a good combo
... getting them high up is challenging (ie. so they hit the top
jelly)... so a colour bomb + striped is good!
