It was a One Eyed one Horned flying purple eater. We created a one eyed monster and filled it with purple pom poms. We let the babies either shake the box or put their hands in and grab for the pom poms. This used the babies problem solving skills. How you may ask.
The babies learned that by either shaking or putting there hands in the box they could grab a pom poms which that texture was fuzzy.
