You have to unlock and grow the frog and clear the blocker over the exit.
You won't be able to grow the frog until it is unlocked, so don't waste a color bomb.
Clearing the blockers at the top of the board will unleash lots of stripes and wraps, the stripes are the most useful so try to clear the left side first if you can.
Get the stripes into the best position to unlock the frog and clear the blocker before you switch them, carefully drop them into position.
Once the frog is unlocked using a color bomb to grow it and then you'll just need to move it out of the way to allow the cherries to drop.
