This thing is "big" at my job.
I work as an accompanist for toddlers
and primary school children. They
gather there before and after school
to play, craft, ...

𝟭. Give each kid a piece of paper
𝟮. Everyone draws a head on the top of
the page. No rules, it can be a human
head, a robot, an alien, an utensil,
...
Also be sure to draw a piece of the
neck.
𝟯. Fold top part of the drawing
forward to hide the head, but still
show the neck
𝟱. Pass it on to the person next to
you
𝟲. On the received drawing, add a body
(chest, arms, belly) and the upper
part of the legs (just a small piece!)
Also no rules here. Make it as
artistic, funny or weird as you want
to.
𝟳. Fold the drawing forward to hide
the body but be sure to still show the
beginnings of the legs
𝟴. Pass it on
𝟵. On the received drawing, add the
legs and feet.
𝟭𝟬. Fold the drawing completely
𝟭𝟭. Pass it on
𝟭𝟮. open the received drawing
𝟭𝟯. Have a laugh :)
