This EFL speaking game is called, "Why is there a monkey in your bag?"
How it works:
A flustered student will say whatever answer comes to their mind.
The teacher will give a follow-up reaction based on the student's answer followed by another question.
And the conversation goes back and forth for a few rounds of questions and answers.
After that, the student will choose another partner and start the conversation over again, and they can change the monkey to something else.
Teach the Language - Take time to explore and correct the language that they use.
Consistency is Key - If you do this on a regular or semi-regular basis, the students will be able to come up with different answers as they get comfortable with the game.
Easter Egg Lessons
Building Community - If lead well by the teacher, your students will feel a part of the community in being able to laugh at themselves and get a bit silly during the exercise.
