2nd board: Make use of the missiles to get the toys. Plan your moves that you don't drop missiles to the bottom. Do not exit before you have 19 toys. Do not use the magic orb until you have to (e.g. due to a single color on exit tile).
3rd board: Break a lot of mud blocks before you make use of Color Bursts so the bottom area is well filled with gem stones.
This level has been changed recently: There are only three toys in the first board now. So you may miss only two toys in the second board! There are less stone blocks in the second board. The stars levels are lower.
