Dressed in his trademark garish animal print with a pencil-thin mustache, Pikotaro swaps out his “I have a pen. I have an apple. Apple pen!” lyrics for “I have a hand. I have a soap. Wash! Wash! Wash! Wash!”

“Clean hand, clean hand,” he adds, displaying his palms before pressing them together, “Pray for People and Peace (PPAP).”

In just three days, the song has racked up over three million views on YouTube, and the comedian‘s Twitter page has been flooded with videos of Japanese children laughing and imitating his handwashing dance.
