Is the ladybug obliged to get physically "in" the plantier? Or is it enough if he is on the playfield tuching the wall of the plantier?
The rules state the following:
The ladybug is validated as being in the zone if all or part of its vertical projection is in a drop zone on the ground or on a planter at the end of the match.
Your Ladybug has the same obligation as a robot, so it may not fully leave the playing area. It just needs to extend some part of it in the vertical projection of the planter to be validated for that planter.
