Cookie Casualty - S1.E11

Gopal, Ying and BoBoiBoy were shocked that it was the World Biscuit Day, because Yaya would ask them to help her make biscuits. As Gopal and Ying ran away, BoBoiBoy Wind had to help Yaya while the other fractions stayed at the cocoa shop. Adu Du tricked BoBoiBoy by making him use fake goat milk that contains "X Solution" -a substance that can make human feelings unstable -as an ingredient for Yaya's biscuits. BoBoiBoy Wind ate one of the contaminated biscuits and distributed all the biscuits without realizing the impact that would be encountered. Yaya's biscuits had caused almost all the people in the town to be insane. The situation became worse as BoBoiBoy Wind ate the biscuits too much, which made him feel an infinite joy. As a result he was transformed to the new power of "BoBoiBoy Cyclone".
