What is one important event that happened during the mesozoic?

During the Mesozoic Era, the Kool-Aid man was born. He entered an epic battle against an army of Sour Patch Men. After 8 years of constant fighting, he was near exhaustion, but almost all of the sour patches had been defeated. Just then, Kool-Aid pulled out a fresh pack of powdered Kool-Aid and dumped it into his tank. Fruit Punch was created. Fruit Punch!Fruit Punch!Fruit Punch!Fruit Punch!Fruit Punch! And then the sour patches were left to just their leader. Kool-Aid told Fruit Punch to step aside. He then jumped into the air and yelled "Kamahameha!" He destroyed Sour Patch King, breaking him into a thousand sour patch kids. The blast was also so powerful that the dinosaurs became extinct.
