What did the cookie say to his friends when he was ready to go?
A: 과자! (gwaja)
You can say “let’s go” when it is time to leave, which is also 가자 (gaja) in Korean.
The phrase 과자 (gwaja) which means snacks or cookies in Korean sounds like 가자 (gaja).
So when a bossy cookie is ready to go, he’ll say to his other cookie friends 과자 (gwaja).
