Levels like 2566 where you rely entirely on butterflies to rescue the Pets can be frustrating and difficult!
Often the color you need for the butterflies just does not appear on the board.
The main trick to passing a level like this, is knowing when to quit the level and start over.
Attempt the level at a time that you have unlimited lives (from the Weather Alert or Mystery Mountain bonus game) or plenty of lives saved from your friends.
First, make some small matches (of only two or three blocks) until four butterflies are on the board.
If you do not get at least two butterflies the same color, (preferably three) or two of one color and two of another, then quit already, it’s not worth wasting time to try and pass.
After you have several the same color try to make big matches in these colors to quickly fill the butterfly.
Having balloons the correct color helps a lot, so does being able to paint the color you need in.
Once you have the first few Pets collected, asses your moves. If you’ve used a lot already, and won’t have enough to rescue all the Pets, quit and start again now.
It can be frustrating, but saves you wasting time playing when you’ll not pass anyway!
If you still have plenty of moves, repeat the process.
Make some small moves until the Butterflies appear, hope you get several the same color and work on filling them in as few moves as possible!
If you have some balloon boosters, or want to buy some, they can help a lot, so can the paint booster to color the blocks.
But even when using boosters keep an eye on your moves and only use them if the level is going well.
