Fun of drums with memory training.
Hit drums in the exact order Robo hit.
"Zun-Zun, Dan-Dan, Jya----n!", a drum-set is a very interesting instrument somehow you hit sequently.
Easy but fun!
Since Robo hit the drum, you should listen and see it, you remember that order.
When Robo said "Try it!", please hit the drums in the exact order as you have seen now.
Now, its a challenge to your memory!
Enjoy!
