BOXBOY! + BOXGIRL! may start off pretty simple, but it gets tricky pretty quickly. So let’s get started on the single-player segment: World 4 Climbing Basics with Up Hook.
As there is a lot to cover, you may stumble across a solution to a level that may either be incomplete or not to the best it could be. If you have any solutions, please be so kind as to email us at email@example.com and we’ll be sure to provide credit if we use it.
Boxes Used: 14
Follow the instructions from the start and use four boxes for the first ledge, three for the second and four for the third.
To get the Crown, make three boxes horizontally and jump to the right so that the rightmost box hooks onto the ledge. By pressing Y, you’ll be able to get the Crown and make it to the door.
Boxes Used: 19
Make a three-boxed hook and pull yourself up to the first ledge. Then to get up to the next ledge and collect the Crown, make a hook go up twice and left twice as shown below.
Make a four-boxed hook for the next ledge and three horizontal boxes and jump to the right. For the last ledge and second Crown, make boxes up twice and left three times like shown below.
Boxes Used: 16
Make three horizontal boxes and jump so that that rightmost box hooks onto the ledge. Then make a three-boxed L and jump to the right so that the bottom-right box lands on the ledge.
For the next gap and the first Crown, make five boxes (right, up x3, right) and jump to use it as a hook on the up-right ledge, allowing you to collect the Crown when you pull yourself up.
And for the last cap and Crown, stand on the edge and make five boxes (right, down, down, right, down) and jump so that the boxes land on the bottom-right ledge, once again allowing you to pick up the Crown as you pull yourself in.
Boxes Used: 23
Make a four-boxed hook to grab onto the first ledge. Then another four to grab the other ledge up-right. From here, make five boxes (left x3, up, left) to hook onto the next ledge and collect the Crown as you pull yourself in.
Make another four-boxed hook to get to the up-right ledge. From up here, make six boxes (left x2, up x3, left), jump and hook onto the top left ledge and pull yourself in, once again collecting the Crown along the way.
Boxes Used: 25
Follow the instructions and keep snaking your way through the gaps. With the Crown, use five boxes to get to the Crown and another five to get up and right to the door.
Boxes Used: 22
Keep snaking your way through, using four and six for the first two sections.
After that, use six boxes to snake into the gap in the wall and from there, use another six boxes to continue following the wall around, collect the Crown and get to the door.
Boxes Used: 34
Use five boxes to snake into the gap in the left wall, six boxes to transfer straight across to the other gap and then five to get up and around.
For the next part, snake up with six boxes into the left gap. Then make six boxes (right x2, up, right, down, right) and collect the Crown as shown below.
Snake your way up and head for the door.
Boxes Used: 45
Make a right hook with four boxes (up x3, right) and then jump into the gap and pull yourself up.
This next part is a bit tricky. Make boxes in this order: right, down, left x4 without letting go of the Y button. This will push BOXBOY out and if you’ve done this correctly, it should look like this…
Now you’ll need to retract the boxes but keep the first one in place and then make a hook to pull yourself up.
For the Crown, play this one as you’d expect. Hook up and around to the top-left alcove and pull yourself up. Then use eight boxes to snake through the crown and across to the other side.
Lastly, we’ll want to use the same technique to move our way across by making boxes in this order: right, down, left x4. Retract it the same way as last time and hook up to the alcove.
In here, make five boxes (left x3, up, left) and drop it. Wiggle your way out, jump up to the farmost left block and jump to grab the Crown and falling back to the right before you get zapped.
Now go back and stand on the second-to-right box and make one block right and up and back into the alcove. Snake the boxes to the left, up and back around towards the door, pull yourself up and your done!
