The candy bombs are always red and no red candies spawn in this level. Also, they are in two inacessible spots, meaning that you have to defuse them all in 25 moves using the candy frog twice.
The candy frog are buried in blockers and is locked.
Feed the frog to use them on isolated bombs.
When the frog is on one of isolated islands, make a colour bomb yourself, and match candies with the same colour of the candy frog to fill it up again. Done that, land the frog in the other island to crush the remaining bombs.
