We don't currently have a walkthrough for this game, but I have managed to find a video walkthrough on Youtube with the solution to your level, if you should still need it.

For level 16, pull the front center block 2 out & 2 right. Pull the switch out and jump on it. Pull the blue block out 1. Jump on it. Jump on the tan blocks. Jump into the hole in the center of the tan blocks and pull the right side 2 to the left. Jump up. Grab the single white block and pull it out 1 to the front, then strech it 1 more to the front.

Hop on and collect flag.

First, pull the pink region of the box (the side where you free the child), then go to the back side of the puzzle and pull out the pink region all the way. You want to make a stair case so that you can get on top of the puzzle and rescue the child. grab the blue block on the bottom right and pull it out completely. Next, grab the white block and pull it out one space. Jump to the left side of the blue block you previously pulled out and push it back in. Now, grab the white block (bottom left piece) and pull it out completely. Climb up the white blocks and push the pink region inwards one space and finish climbing up the puzzle until you reach the top of it and rescue the child! Hope that helps. You're not the only one having issues with that puzzle. I got stuck on this one for a few hours. Good luck completing the rest of the game!
