this is the first level where there is this trick . figure it out , avoid the guards and finish the level .
@meko I figured as much. Either that or on top of the center structure. Spoiler: Almost I managed to throw B through the hole, but get him in it -and out?- seems quite an arrangement
Spoiler: Gtb you put b in the hole,he will stay in the hole.the guards will pass and you tap on the win
