BOXBOY! + BOXGIRL! may start off pretty simple, but it gets tricky pretty quickly. So let’s get started on the co-op segment: World 10 (Warp Portal Peekaboo).

Step through the first warp portals and before BOXGIRL steps through the second, have BOXBOY place a single box underneath to cross the spikes.
Next, have one player stand on top of the other and the bottom player make three boxes above themselves (without letting go). Then the top player can make a three-boxed backwards L and throw it onto the spikes. Have the bottom player retract the boxes and then have both players go through the portal. With one player standing on top of the other again, the top player can now jump to grab the Crown.
Go back through the warp portal and make for the door.

The bottom player can now make their way through, with the top player going back through the warp portal and doing the same thing.
For the Crown and the door, have one player stand on top of the other and jump to the ledge up top. Then have the bottom player go down into the ditch and make a three-boxed backwards L and hold it.

Now have BOXGIRL go through the square portal like the previous time and head down to BOXBOY. Now have BOXBOY stand on top of BOXBOY and have BOXGIRL make four boxes upwards (but don’t let go of them) so that BOXBOY can get to the blue silhouette. Retract the boxes and have BOXBOY join her.
Have BOXBOY make two boxes horizontally in the bottom-left corner. Then have BOXBOY stand on top of BOXGIRL and jump into the circle warp tile. Situate BOXBOY in the bottom-left corner of the right side and have BOXGIRL stand on the right box and make four boxes in this order: left, down, left, down. This will warp her over to the other side with the bottom box landing on top of BOXBOY. Then you’ll need to have BOXBOY jump up-right so that BOXGIRL lands up on the ledge.

Have one player make a three-boxed backwards L next to the blue silhouette platform blocks. Then with that player on top of the other, make for the top box and have the bottom player make three boxes upwards (only to retract them afterwards), allowing the top player to go through the square warp portal. That player will then fall onto the blue button, activating the blue platforms. Then have the player that’s left behind stand on them and make a three-boxed forward facing L to use as steps to get up to the portal.
Have BOXGIRL place a box onto the blue button. Then have BOXBOY make three boxes to the right and one up (don’t let them go) so that BOXGIRL can go through the circle warp portal. She will then drop onto the red button so that BOXBOY can retract the boxes and grab the Crown.
Have BOXBOY make a three-boxed backwards L and proceed through the circle portal.
For the next section, have one player make a few boxes to the right without letting go so the other player can make their way over. Then retract the boxes and have the other player do the same thing so that both players are on the other side. Have one player on top of the other; the top player needs to make four boxes on top of themselves to the left and the bottom player makes four boxes upwards (only to retract them once the top player has gone through the portal). When that happens, the top player will be hooked onto the ledge that has the Crown, so pull them in.
Drop down and land on the blue button so that the player on the left can make a three-boxed left hook up to the blue blocks and then make a three-boxed backwards L to use as stairs up to the portal.
