Invite each person to draw a small creature and choose a movement for it. An adult can handle devices while everyone contributes ideas and decides what they are comfortable sharing.
Try this
Put the characters in an imaginary garden and take turns describing what each one does. End by asking everyone which movement made their character feel most recognizable.
Take it further
Prepare paper and drawing tools before the activity and agree on a comfortable stopping time. A family member who prefers not to draw can suggest a setting or help describe a character's movement.
