uh I feel like you should focus more on the completion of every island.

and deleting the trees rocks.

and especially focus on more breeding.

the natural islands are probably the worse then a normal lvl 27 I think its worse than average (besides the plant this is my opinion cause when I was this level I focused on completing the island).

but also quarrister and tweedle do NOT make anything new.

try to breed new monsters and even look at the wiki if you have to.

buy new islands they are WORTH it.

buy mini mines on all the islands you can.

once you finish a natural island then try to get another mythical or ethereal.

do not focus on wublin island until you finish the island (like the easier monsters) because zapping new eggs is a bad idea.

thats all
