Here is our 3 star walkthrough video strategy for Amazing Alex level 4-20 The Treehouse, also called “The Dog Returns”. Your goal is to drop all four 8-balls through the hole in the floor. The idea is pretty simple, but the execution is a bit more challenging.
If you have a different strategy for completing this level feel free to leave a comment below.
put the scale, punching thing, and the bottom left pipe just like the video, now put a pipe from the top right plank leading to the middle, and another pipe from there to the star and into the hole, good luck!
