Improvising
In each episode of Boohbah, children give the Storypeople a present. When the gift shows up in Storyworld, it sparks the action.

Directions
Pick an object or the gift given to the Storypeople. Hand it to your child (or in a group, around the circle). Each person who handles the object has to do something different with it or make something different from it. So, for example, a ribbon could be used to tie shoes. Or it could be the tail of a small kite. Or the smile of a smiley face. Or a jumprope for insects. etc. The more imaginative and silly, the better. The game continues until you and your child (or everyone in the circle) runs out of ideas.

You might follow up by choosing one of the ideas and actually making it from the original object you passed.
