That is a good question and I agree that we could do with a new blocker to make the game more interesting.
But adding to this, at which level do blockers come into the game? For example, I really do like the chewing gum, the liquorice swirls are good too, and the jelly jars aren't THAT bad. At which level do these first appear? Many players are now forced to stop playing by the levels having been made too hard, so perhaps introducing new blockers or introducing more of the existing ones on earlier levels would be a good idea to keep the interest of players. Just don't overdo the quantity!
As for the sour sculls....they should be wiped out completely in my opinion.
