The kids head to the beautiful Meadow Gigantico to play tag - when they discover the meadow isn't all that beautiful anymore. Overnight somebody has completely trashed the place - literally - and now the park's most pristine corner is covered with garbage.

With Yoko's help the clean up turns into a game that leads to something Different from their initial expectations, including finding out who caused that mess in the first place.
