I can get the 2 bears at bottom but not that 3rd center one!! Been on this level forever and just want to move on. HOW can I get that 3rd bear off the wood/
If you go to the link @Pummy Raj provided and scroll down to Level 1320, you will see how I used the line blasters to get those two outside Pets, then filled the butterfly to save the third.
Butterflies need at least 16 blocks to fill them, but the smaller the groups of blocks and the longer time you take can mean many more than 16!
