One child is a king, the others say:
-Hello, King Ping
and he answers:
-Hello, Kids Bits. And then he asks:
- Where were you?
The children answer:
-We were there and did that. (And they imitate the action they did, e.g. they jump, swim...)
The king is to guess what they did.
The children can imitate an action or an animal depending on what they agreed before they come to the king.
