World 3 - Level 3
Kaboom!s in my Garden
Push the two boxes marked in yellow to the yellow "X"s (building one bridge) to get the Kaboom! to reverse direction and walk along the outer wall. Now move the remaining yellow wood box along the yellow path, wait for Kaboom! and detonate it at the garden's entrance. Inside the garden, move boxes along the blue arrows to allow them to be retrieved one by one.
Use four boxes to build a long bridge (blue "X"s), the fifth box to deflect the Rainbow Spirit (make sure it is toward the right of the box, i.e. in the blue circle). The spirit will collect some of the Rainbow coins in the upper left corner for you, allowing access to the rest. Use the sixth box to build a bridge at the green "X", collect remaining coins, and exit.
