You need to remove all the jelly but most of it is covered by chocolate.
At the start the chocolate is confined by locked cells, but once the two bottom cells, left and right, are opened the chocolate is released and quickly takes over.
With so many holes in the board moves at the bottom are limited so keeping the chocolate under control is very difficult.
The best way to deal with the chocolate is to make as many special candies as possible and blast it as many times as possible until it's destroyed. Stripe/wrap combos are good, as is a colour bomb switched with any other special candy. The fish in the middle will help a little, but better if you can switch the fish with a stripe or a wrap, as this will give you 3 stripes or 3 wraps, which are obviously better than normal fish.
Once the chocolate is gone work on making more combos to get the jelly. Stripes and wrap combos are best, or colour bomb with either of them..
If you are struggling with level 461 you may find a jelly fish booster helps.
