Mark the area with Dimex caps, hide 30 Dimex pens, divide the Dimexians into two groups: Team Piip and Team Pööp. Name the searchers from each group. Everyone looks for the pens, when they find one they have to go next to it and shout the name of their group, i.e. “piip piip piip” or “pööp pööp pööp” until the searcher comes over and grabs the pen into their pocket. If there are more people around the pen, the group with the most members there wins.
